• WFN has been providing DNA Information, Websites, and Administration to FTDNA Surname DNA Projects since 2004 (About Us).
• FTDNA and WFN have a long-standing relationship (Learn more).

Participants with surname Dewees, Deweese, Deweess, Dewese, Duese will test DNA  marker sites on the their Y chromosome to determine their common ancestry.

The principal goal of the Dewees Surname Project, initiated on June 7, 2010, is to use Y chromosome variation among Dewees(e) males to test the hypothesis that virtually all Dewees(e) families in America are descended from a single ancestral male, most likely Garrett Hendricks de Wees, who immigrated from The Netherlands to New Amsterdam (NYC) in about 1663.

 A secondary goal is to determine if Dewees(e) families sort out into sub groups, specifically into three lineages from  the purported sons of Garrett Hendricks deWees- William, Cornelius, and Lewis (Lambert).

A final goal: the Y chromosome test by Family Tree DNA provides information to verify the Y chromosome Haplogroup to which the Dewees(e) family belongs.  This information is used to determine the deep ancestral point of origin and migration history for the Dewees(e)  paternal line.

Recommendations for Participants:
For the Dewees Surname Project we are recommending participants use the Y-DNA37 test kit from www.familytreedna.com. It includes a balanced panel of 37 genetic markers on the Y chromosome and is the recommended test to trace the paternal ancestry of males for genealogical purposes.

Funding Available:
Limited funds from the Dewees group General Fund are available to help defray costs for new participants based on need.  Please contact Project Administrator.
