Daughter of Jan van Groenewegen; Common Ancestor (Consanguinity) to Past American Presidents?

Project Tags

view all


my parents were living in the United States in 2014 with my two brothers and ever since my father followed with much interest american politics (unfortunately)

anyway back to this project, it is intriguing that "nearly" ALL of the past american presidents - way back to george washington and currently, Obama, they have a common ancestor i.e. Daughter of Jan van Groenewegen, which happens to be my ancestor too! The common ancestor is still much of a mystery and we really hope by doing this project it would help shed some light.

hence, being linked to the past american presidents... no doubt, this profile presents to us a very important piece to the history of genealogy...

The geni profile for the daughter of Jan van Groenewegen

16/June/2016 (update): two presidential candidates, Hillary (1) and Donald (2) are also related to this profile as per below,



hence, whoever wins the election, either way, this project would still remain relevant as a "predictor" to future presidential candidates?! and perhaps may even be a "predictor" for president of the USA...

as of today 22 Nov 2020, Joe Biden, 46th President of the USA (President Elect Joe Biden) is not in any way related to the Daughter of Jan Van Groenwegen (Project).
