Yes Allan. I go back to 1770 via paper but I think a good genealogist would get me further.
I really can't see the point of going back into pre-history via DNA because it simply proves that you have a genetic match with a whole bunch of folk. They are not relatives in any real sense, in that you don't know them, don't have a connection to them!
I would be much more interested in finding some of my living relatives but the restrictions on publication of census detail restricts that process.
