DNA

Y-DNA

A Y chromosome DNA test (Y-DNA test) is a genealogical DNA test which is used to explore a man's patrilineal or direct father's-line ancestry. The Y chromosome, like the patrilineal surname, passes down virtually unchanged from father to son.

I have started looking at Y-DNA of the Easterbrook name to trace the origins back further than is possible with the existing written records (10+ generations). If you are interested in taking part in this interesting research project then take a look at the Easterbrook DNA Project. You will need to have an unbroken male Easterbrook line for Y-DNA testing and initially I am mostly looking for those who can trace their roots back to the Holne and Buckfastleigh areas of Dartmoor and in particular any males decended from Family 253 . Alternativily if your ancestors are from Devon but are not direct male descendants of an Easterbrook you may be interested in the more general Devon DNA Project.

Currently I don't have enough results to present any findings here.

Mitocrondrial DNA

A mitochondrial DNA test (mtDNA test) traces a person's matrilineal or mother-line ancestry using the DNA in his or her mitochondria. mtDNA is passed down by the mother unchanged, to all her children, both male and female. A mitochondrial DNA test, can therefore be taken by both men and women.

I have not explored mtDNA as it follows the female line and is therefore not useful for surname research.

Autosomal DNA

Autosomal DNA is a term used in genetic genealogy to describe DNA which is inherited from the autosomal chromosomes. An autosome is any of the numbered chromosomes, as opposed to the sex chromosomes. Humans have 22 pairs of autosomes and one pair of sex chromosomes (the X chromosome and the Y chromosome).

I am currently examing the DNA test results on Ancestry and GEDmatch. Currently there are no useful results relating to the Easterbrook surname but the DNA databases are growing at a significant rate so this is likely to change. I do have many matches but the nearest are still several steps away from a direct Easterbrook line.
