DNA testing - genetic genealogy

[coombs]

I dont think women inherit their Y DNA off their father.

I have the same mt DNA as my mum who inherited it off her mum. The line starting with mum in therms of birthplace is Essex, Durham, London, Sussex then it remains in Sussex. My paternal line starting with dad is Essex, Essex, Suffolk and it then remains in Suffolk until at least as far back as the 1660s. As I am male I have my dads Y DNA. But I will not pass on my mt DNA.

I thought Coombes that women were XX chromosomes, men YX. Marcie, this is my problem, but it goes back to around 1776, and there is much paper work but none of it connects.

Mine only goes back to about late 1800 early 1900's, does that mean that I have more of a chance of finding my connections then.?

OK.   I can understand most of what's been said but, could somebody explain to me in words of one sylable  (    ) how I could find through DNA testing my grandfathers line??   He was illegitimate and took his mothers name, so we don't know his father at all.   Would DNA testing help in this instance??

  Would DNA testing help in this instance??

Only if others from his line also entered their DNA records into the database.

Thanks Falkyrn

Would that be from my side of the family such as my mum or from his side such as a grandson or grgrgrandson etc.
Obviously my grandad is dead and he would have been the nearest to prove one way or the other but probably on the same lines as Falkryn stated in that posting.

Tephra,

In short No because Y dna needs to come from the male line so unless you knew who his father was then you couldnt do it.  YOu could have MtA test done but this is not as accurate because this uses the female X chromosome which only passes through the female line

Other than exhumation I think there might sometimes be a way of getting the DNA from the dead. Many people keep souvenirs of relatives, a lock of hair etc. would I think be a possibility for DNA testing, but it would really be a lucky chance.
