About us

BACKGROUND:  This project was launched in 2004 by Charles Kerchner, a Peter Delong descendant, to determine the Y-DNA chromosome markers for various unlinked Delong / Delang / Delanghe family groups and similar sounding (in English) family surname groups in the USA, and to determine if any of them have a theoretical common male ancestor in Europe in the last 300-500 years. A French Huguenot family name which arrived in America in the early 1700s.

WHO CAN JOIN: Delong surnamed males (or a Long family names lines who through spelling variations over time the family name changed from Delong to Long or similar sounding or spelled) or someone sponsoring a Delong surnamed or similar sounding/spelling surnamed male. Only males can be tested for this project since only males have Y-DNA. However a female researcher can sponsor a male who is related to her, i.e., a brother, father, uncle, great-uncle, cousin, etc., as long as that male was born with a surname being studied in this project.  The name of the person being tested, or at least the male's first initial along with the spelling he uses for his Delong or equivalent surname must be provided to be in this project. Due to the new privacy regulations adopted by FamilyTreeDNA in May 2018, when you join this project you must be willing to grant the Project Admin "Limited Access" to view your test results data in order to facilitate sharing, comparing, and grouping of your data for the benefit of this project and yourself.
