My DNA y-chromosome test shows that I am Haplogroup G2a (P15). This was done by the Genographic Project run by National Geographic and IBM.I am in the US. I can research back only to my 7th great-grandfather, Joseph COLLINGS who died, about 60 yrs old, in 1757 in Middletown, Monmouth Co., New Jersey, USA. I have no idea who his father was, after 34 years of research. Where did many of the COLLINGS family live in the UK in the 1600s? Maybe someone else has my same DNA. Thanks, Joe Collins (changed from COLLINGS).
