I had done some genealogy research off and on over the last 3.5 years or so, but in the spring, about the same time, my oldest brother and I both started thinking about Dad's impending 80th birthday and asked if he would get DNA tested. I did a Y-Dna test of him via one company and DB did the ancestry test of him. We were able to confirm some interesting speculations we'd run into (yes, a 2nd great grandmother really was born when her father was 60 and her mother was 56) and some others were in some puzzling roadblocks (on the Y-dna line, his 4th great grandfather isn't related to who we thought was the 8th great grandfather, so someone between them was either illegitimate or adopted). We also found out that my parents moved in 1998 to the county that the Y-line originally settled in Indiana in 1817. We married in with other founding families for the county. Our branch moved from there to the next county west during the 1860s-1900s (there were a dozen kids and they slowly moved that way until my 2nd great grandfather died there at 79. My brother and I went to the genealogy library for the original county and spent 3 hours there Friday and barely scratched the surface. Can't wait to go again (2.5 hour drive for me, but its 15 mins from my Dad and brothers, so I will go again when I go visit them sometime).
On Dad's side, we can trace to at least his 2nd great grandparents on all sides, and includes an 8th great grandfather who was a Quaker martyr in England. His widow remarried a friend of William Penn and they were early settlers to Pennsylvania. The house they lived in is still standing and I definitely plan to visit. We are DNA confirmed to those. Family lore said Dad should be 1/8 native american, but the only family we can't go back farther than that on came from Germany, so that seems pretty doubtful.
I later did the ancestry test on myself to find out more about my Mom's family. I can't find much of anything about her Dad's family, except things we already knew, and no DNA matches (my grandfather was born in 1892 and his father in Germany in 1843, so records are more difficult to find). Honestly, I wouldn't be surprised to find we aren't dna related to them, though. My maternal grandmothers side is a little more fruitful, but very confused by there being another man with a very similar name (Henry Saurwein vs Henry Sauerweine) born within 20 miles, in the same year. I've being using census matching and which children are listed with whom. My Henry Sauerweine has a harder to trace father and mother, and I dead-end on them. I can go to my 3rd great grandparents on her mother's side, by DNA, but that still only gets us to the early 1800s. Still, better than many can do, and I've had a lot of fun doing it.
