Dram, thank you for those answers to my questions! I'm thinking I might have DNA testing done just to see if anything of interest comes up. While my Scot ancestry is through my paternal grandmother, I'm curious to see how much further I could go and/or what may be proved or disproved. Also would like to see if I can glean any information on my paternal grandfather's line, which is where I've hit a wall. All I know is that he's German.
Any suggestions for agencies and/or specific tests? From what I see here, the more markers, the more accurate (and I imagine the more expensive.)
Fascinating stuff - DNA! Wish me luck. Thanks again.
