Hello to all VV descendants! There is no evidence that Lambert Van Valkenburg who m. Annetje Jacobse, had a father named Jochem.
Lambert has not been found in *ANY* primary source documents with any patronymic, let alone one of Jochemse. I have many court documents relating to Lambert and his name is always given as "Lambert Van Valkenburg" (with variant spellings). In the only two baptismal records found in New Netherland (in the Reformed Dutch Church New Amsterdam, which is present day NY City) Lambert uses *no* patronymic, thus we have no way of determining his father's name.
As Tim Tillyer pointed out in his message, findings published in the New York Genealogical & Biographical Record Vol. 112, #2 p. 79 indicate that Lambert Van Valckenburch [sic] was bpt at Millen on 16 Apr 1614 to Lambert Dryeskens [Andrieskens] van Valckenburch and wife Maria.
I have quite a bit of info on Lambert and his line at my homepage, The Olive Tree Genealogy at http://www.rootsweb.com/~ote/http://www.rootsweb.com/~ote/
