ROOTSTECH 25–27 FEBRUARY 2021: Don’t Miss It!

For those who are not aware: ROOTSTECH Connect is the world’s largest family-history technology conference. And this year it will be a completely FREE and VIRTUAL experience! Hundreds of amazing sessions will be available online during and also after RootsTech Connect has ended on February 27th! Many of those sessions will offer precious insight for Africans and Afro-descendants in their quest to Trace African Roots! All it takes to attend is a free online registration. Right now more than 315,000 participants from more than 200 countries and territories worldwide have already registered! For more details:


I am very honoured, grateful and excited to also be part of this tremendous event! Because I will be giving an presentation as well! I will be demonstrating my scanning and filtering method to zoom into African matches or any other type of lineage you are interested in researching. I originally devised this technique in 2017. And I have been using it ever since to conduct my ongoing African DNA matches surveys. After registering for ROOTSTECH you should be able to find my class listed in the various search menus. But you can also just directly see it by following the link provided above.

If you are having trouble finding your African DNA cousins this can hopefully offer you a great opportunity to systematically look for your African DNA matches! During the event there will be an occasion to ask any questions by way of a chatroom. But of course you can also always reach me here on my blog if anything needs clarification or just to leave a comment. See also:

In the remaining part of this blog post I will show a few slides for a sneak preview 😉 Furthermore I will also provide all materials/links mentioned during my presentation. For those intending to watch my presentation: Thank you for your attention! I will be rooting for you that the ethnic filtering method I have discussed will be beneficial for you as well! 


Let’s get this cocktail party started! 😉

The Mozambique connection on Ancestry & MyHeritage

Mozambique is a somewhat overlooked country of origin for many Afro-descendants. To be sure the Trans-Atlantic Slave Trade with Southeast Africa was relatively smaller in scope than with either West or Central Africa. Still according to most recent estimates it involved almost half a million people (see this overview from the TAST database). Especially for Brazilians, Haitians and Cubans Mozambican lineage might be considerable in some cases. Plus also the Indian Ocean Slave trade is to be taken into account. Which most likely resulted in a dispersion of a similar number of Mozambicans (see this overview, taken from this paper). Especially into South Africa and the Indian Ocean Islands: such as Mauritius, Réunion and Madagascar. But also to the Middle East and into South Asia and beyond even. For more details:

I found 12 most likely African matches for a person who is himself 1/2 Mozambican and 1/2 Portuguese. Most of these matches actually were likewise of mixed background. With the majority being from South Africa (6x). But also tellingly one single close match from presumably Pemba, Mozambique! MyHeritage provides a very useful filtering tool which allowed me to zoom into shared East African DNA segments among this person’s DNA matches.


Then again some people might also have Mozambican ancestry due to recent migrations. In the last couple of months I have been given access to DNA results which reveal an already confirmed Mozambique connection for two people of mixed background. With very fascinating outcomes! As well as useful implications for other people wanting to learn more about their own possibly Mozambican lineage.

The first person is living in the Netherlands (like me). Both of his parents were born in Mozambique. But going back two generations his father’s grandparents are all of Portuguese descent. While his mother’s family has been living in Mozambique for as long as can be traced back. But her family tree does contain at least two persons who were born in India and migrated to Mozambique as well. When it was still under Portuguese rule. All in all a very fascinating tale of migration across several continents! This person tested with MyHeritage and he has been featured in a Dutch documentary series called “Identity”. I was actually honoured to also contribute to this documentary which was shot in my birth place Rotterdam. The actual day of filming being the 5th of July which happens to be Cape Verde’s Day of Independence! Highly symbolic for me therefore 😉 1 See also:

These are the recently updated AncestryDNA results of a person whose father is from Mozambique. His Southeast African DNA is clearly indicated by his main regions, incl. also “Eastern Bantu”! Another intriguing aspect is that this person actually also has a Cape Verdean connection by way of São Tomé & Principe. This is revealed by a very distinctive score of 6% “Senegal”. Probably also to be combined with the “Portugal” & “Spain” scores. Highlighting that regional admixture DOES matter!


The other person is a DNA cousin of mine on Ancestry whose mother was born in São Tomé & Principe while his father is from Mozambique. I am related to him by way of a mutual Cape Verdean relative who migrated to São Tomé & Principe as a contract labourer during the first half of the 1900’s. São Tomé & Principe is a former Portuguese colony just like Cape Verde and Mozambique. But nowadays it is an independent island state located nearby Gabon in the Gulf of Guinea. Just like Angolans and Mozambicans many Cape Verdeans ended up settling in São Tomé & Principe during the Portuguese colonial time. Notoriously being employed under very harsh circumstances on the cocoa plantations of São Tomé & Principe. It therefore still has a sizeable community of Cape Verdean descendants. Their continued longing for their motherland has been made world famous by the song “Sodad” by Cesaria Evora (see this video clip).

This blog post will describe the DNA results of both persons. Seeking to demonstrate in particular how correlating regional admixture analysis with DNA matches can be rewarding and mutually reinforcing in many cases. In addition I will also discuss my experience with MyHeritage. As I have myself not tested with this company. And so this was the first time I had the chance to get acquainted with several of its features. Allowing me to also make some cross-comparisons with Ancestry.

  • Mozambican Connection on MyHeritage
  • Mozambican Connection on Ancestry
  • Comparing Ancestry with MyHeritage
    1. MyHeritage is distorting Central & Southeast African DNA
    2. Ancestry offers greater potential to find African matches
    3. MyHeritage provides more advanced filtering tools

ROOTS.NL (S1E3) – True Colours (Dutch Race Relations)


Cover of Dutch Genealogy magazine in which Annemieke’s research was featured in 2015. The portrait is of a Dutch Countess with her African servant named Cocquamar Crenequie.


“ The exhibition “From the Shadows, new light on African servants at Weesper notables,” opened at the Weesp Museum to a small crowd of townspeople on March 25, fittingly one day before the International Day of Remembrance of the Victims of Slavery and the Transatlantic Slave Trade. It aims to confront Dutch people with the possibility that their history contains more nuances than they are probably aware of.” […]

Another prominent figure who appears in the exhibition is Christiaan van der Vegt, servant in the 18th century to Weesp mayor Abraham D’Arrest. What Christiaan’s African name was and how he ended up in the town is unknown, but he had married a girl from Weesp and they had ten children. “Imagine the surprise of (white) Dutch woman Annemieke van der Vegt when she in 2013 – 250 years later – unsuspectedly decided to research her past and came to find that she is a direct descendant of this African servant.” (Daily Herald Sint Maarten, april 4th 2017)


In the previous parts of my blogseries about Annemieke van der Vegt and her search for her West African forefather (Christiaan van der Vegt, ca.1750-1825) I have already discussed the following topics:

In this third part I will attempt to shed more light on the following question: how does Christiaan’s life story fit in the currentday discussions on race relations within Dutch society? I will also include other known cases of African or Afro-descended persons living in the Netherlands before the 1900’s. Specifically I will deal with the hotly debated “Zwarte Piet” topic and the origins of this increasingly contested figure of Dutch folklore. Lastly I will describe the potential role DNA testing might play in uncovering the genetic legacy of the colonial past of the Netherlands. Not only for Dutch people but also across the Afro-Diaspora and even within Africa.

  1. Seeking a broader context for Annemieke’s research
    • Weesp & its Ghanaian connection
    • African presence in the Netherlands earlier than imagined?
  2. Tracing the Roots of “Zwarte Piet”
    • Were African servants such as Christiaan the inspiration for Zwarte Piet?
    • Dutch Tolerance showing true colours?
    • Amsterdam leading the pack (again)?
    • My personal perspective on Christiaan’s lifestory
  3. Dutch colonial legacy revealed by DNA testing & genealogy
    • African ancestry among (ethnic) Dutch people
    • Dutch ancestry across the Afro-Diaspora
    • Dutch ancestry in Ghana

ROOTS.NL (S1E2) – Searching for Gold

This is the second post in my blogseries about a Dutch woman (Annemieke van der Vegt) who is in an ongoing search for her West African forefather (named Christiaan van der Vegt after his baptization in 1777). In the first post I discussed how AncestryDNA can be very helpful when trying to trace African ancestry. It provided Annemieke with conclusive evidence of her African genetic inheritance. Furthermore I gave an overview of Annemiekes astonishing archival research findings sofar. Follow these links for more details:

Many fascinating details about Christiaan’s life have been uncovered by Annemieke already. The one thing she is still very eager to discover though is his original name given to him by his parents. And also his ethnic identity before getting caught up in the slave trade as a child and being forcibly relocated to the Netherlands. This blog post will therefore be centered around the question facing not only Annemieke but many Afro-descendants in the Diaspora: Is it possible to pinpoint a plausible ethnic origin for one’s African bloodline?

ROOTS.NL (S1E1) – Dutch woman in search for West African forefather


AncestryDNA results of a Dutch person with one single African ancestor, Christiaan van der Vegt, possibly depicted in the drawing (c. 1760) to the left.


“Christiaan was born around 1743. This I know by his letter from 1815: (translated from Dutch)

“Letting you gratefully know Christiaan van der Vecht, born at the Coast of Guinea, 73 years of age and living in Weesp.”

Where at the Coast of Guinea he was born I don’t know and also how he came to the Netherlands is unknown to me.”

My name is Annemieke van der Vegt and I am a grand-, grand-, grand-, granddaughter (his grand-, grandson is my grand-, grandfather) of Christiaan van der Vegt”

For the complete story see: What was Christiaan’s name?


In this blog post and two following ones i will feature the highly remarkable research findings of a Dutch woman who is in an ongoing search for her West African forefather. By simply googling her surname in 1998 she discovered that she had a West African ancestor she was previously unaware of!  She found out eventually by way of archival research that her West African forefather had been a personal servant of several members of the Dutch royal family of Orange-Nassau (at the time of his employment the Netherlands were still a Republic though). And later on (c. 1765) he was also a servant of the mayor of Weesp, a small town near Amsterdam. Most likely he had been only a child when he was brought to the Netherlands. As an adult he had several other jobs and married a Dutch woman with whom he had 10 children. He was baptized as Christiaan van der Vegt in 1777. His original African name and African ethnic identity remain unknown for now but his Dutch ggg-granddaughter, Annemieke van der Vegt, is determined to find out.

The strongly personal motivation of this sixth generation Dutch descendant to uncover the life story of her West African forefather is very inspirational. At the same time her astoundingly diligent research is proving to also have great relevance for many other people. Her work has been put in the spotlight in several Dutch media articles already, incl. the national newspaper Volkskrant, as well as a national genealogy journal. The Weesp museum has recently held a special exposition about Christiaan and three other Dutch Africans who are known to have lived in Weesp around the same time (mid 1700’s). Also historians (both within the Netherlands and internationally) are eager to tap into her specialized field of knowledge which she has been steadily compiling on her amazing blog since 2013. This was the year that marked the 150th anniversary of Dutch abolition of slavery in 1863.

If you continue reading i will discuss the following topics:

  1. What can be learnt from AncestryDNA when trying to trace African ancestry? (ROOTS.NL, part 1)
  2. Is it possible to find a plausible ethnic background for Christiaan? (ROOTS.NL, part 2, Searching for Gold)
  3. How does Christiaan’s life story relate to the currentday discussions on racism within Dutch society? (ROOTS.NL, part 3, True Colours) Continue reading
