To summarise what we know, we now have three men who have been tested. They are:Andrew John Swinfield born 1957 Sydney, NSW Family 3A
Derrick George Joseph Swinfield born 1928
Paul Frederick Swinfield born 1957 Crayford, Kent Family 4 & 13
Andrew & Derrick match at 29 of 32 markersPaul & Derrick match at 31 of 32 markers
Andrew & Paul match at 34 of 37 markers
Andrew’s ancestor was William (1804-1876) who emigrated to NSW in 1848. He is the forebear of all living Swinfields in Australia. Paul’s great-great-grandfather, George Swinfield (born 1825), remained in England after his two oldest brothers, William and John (1806-1874), travelled to the other side of the World.
Derrick is part of my branch of the Swinfields, Family 5, an equally large lineage. Unlike me, through the unfortunate illegitimacy which resulted in my great-grandfather, in 1841 (see Part 6 of the blog), he would appear to have a “typical” Swinfield Y-chromosome. He has inherited this from his direct male ancestors. His almost exact match with the two representatives of Family 3 & 4 strongly argues that the two largest pedigrees are branches of one much larger family tree. If only records had survived from that early, it would be possible to show that all those named Swinfield descend from a single ancestor who assumed our surname in about the 13th century when names became hereditary.
It would appear that the "Swinfield haplotype" is:
|391||10 or 11||464b||16|
|385a||11||464c||16 or 17|
|459b||9 or 10||CDYa||35|
|455||11||CDYb||36 or 37|
We now need to test men from other branches to see if they have the same haplotype too. Volunteers please raise your hands!
