Henk, the children I have for Berend Jelkes Bos and Grietje Folman aka Geertje Freerks Toornman
are: Annechiend Berents Bos, Geertruid Berends Bos, Hinderkien Berends Bos, Jelke Berends Bos, Frederika Berends Bos, and Fokkien Berends Bos.
They married in Wildervank on Aug. 12, 1797 but later the family was in Wildervank, then Nieuw Buinen.
The last child, Fokkien, was born in Nieuw Pekela in 1816. This information is from Genlias.
Hope this helps. Diane Harkins
