I have enough links without spending $$$ on DNA. Because my father came from an area in Pennsylvania where records were kept, I found that some of my family can be traced directly back to New Jersey, Delaware, Mass.   etc., during the early colonies. There are pretty good records of that small group of early settlers, so just by luck I can trace several lines back to England, Scotland, Wales, France, Netherlands... and even to Germany. It seems I am distantly related to a couple governors of Mass. Bay colony (Dudley & Bradstreet) and to Winston Churchill, the Windsors, a couple sheriffs of Nottingham and several other 'names'... almost always by 3rd daughters and 4th sons....etc. *IF* all the links I found prove accurate, a couple lines go back to the 1200s & 1300s.
   It seems once you get 'X' far back with some prominent name, there were good records going back further. In my Pennsylvania links, 3 or 4 names were the ones which mattered. Axtell, Clutter, Wade, Sanders,..and away we go!

This page http://ancestortracks.com/WashingtonCo1856.html got me to this map http://ancestortracks.com/WashingtonCo,Barker_1856/MorrisTwp.jpg, which has actual locations of some of my family.

If you know (in the USA)(and in the UK) where various ancestors are buried, there are cemetery photos and links to help.

All of this is, of course, a departure from 'fun with DNA', but genealogy in general is fascinating if you are fortunate to have a starting point.
