I have been researching the Blair family from Lancaster County, PA. My earliest ancestor is John Blair, born 1819/1820. He married Margaret Skiles. John was MIA during the Civil War, but his military records indicate that he left to go to back to camp because he was injured, and wasn't seen again, in 1864 I believe. In the 1850 census, it has the family living in Upper Leacock Township. I've hit quite the brick wall with trying to find out who John's parents were. Any help would be appreciated. Thanks! Kelly
