Johanna 'Jannetje' van Wijk - Not certain that Claesje's Jannetje is Jannetje van Wyk

Putting together all the data we have & using the FFYP as well, http://www.e-family.co.za/ffy/g8/p8113.htm
it seems to me that we must acknowledge that although 'Maaij' Claesje van Angola had a daughter called Jannetje by an unknown Christian father; we do not have direct sources to validate that this Jannetje is the same as Jannetje van Wyk.

And it is Jannetje van Wyk whose descendant has tested as L4b2b.

It's pretty tantalising, but not certain.

We also need some Source Documentation for the father on geni: Willem van Wyk
