I am Ben Van Beurden and live in Flanders (Belgium)but my Y-ancestors lived in Holland.
It seems that the Van Beurden Family is related with a branch of the Willamson's who belong tosub-haplogroup,G2a3b2b (according to Family Tree DNA)and descending from Peter Williamson b.c. 1700 New Amsterdam NY
I hope to share information with you; in the first place: genealogical date. Perhaps it will be possible to trace our MRCA (most recent common ancestor).
