Y-DNA Results for Winterton

A cousin has kindly tested his Y chromosome at FamilyTreeDNA for the family's Y-DNA study of the surname Winterton.  (Duryea, Lutter, and ODonnell have already tested.)

The last person named Winterton in my line was Laura Winterton (1891-1962), my great grandmother.  A direct male descendant of Laura's brother was the donor of this DNA.  To test the Y chromosome of ancestors in your tree, you need to find a living direct male descendant of the male ancestor of interest.  This living cousin has a Y chromosome identical or almost identical to Laura's father, William Winterton (1862-1932).

The most distant Winterton ancestor I have traced to date was William Winterton, whose will was probated in New York City in 1785.  Y-DNA testing can boost research back in time, beyond this William.

235 other people "match" my cousin at the 25 marker level.  None trace their ancestry back to someone named Winterton.  One person matches at the next and highest level we tested, 37 markers.  His ancestry traces back to Little Thurlow in Suffolk, England.  I suspect English roots for William Winterton, so this is a good place to start looking for him.

When working with DNA cousins, look for the same geographical location.  Surnames will vary and change.  You have an ancestor in common with a DNA match because your ancestral lines crossed at the same time in the same place, regardless of the surname subsequent generations were called.

Only match at the 37 marker level
