With the help of my Aunt, I've just begun digging into my family tree, she has passed on research to me that may interest you. I was searching the name David Livingston because he was my Great, Great, Great, Great Grandfather. I then have his parents as Andrew & Elizabeth (Groff) Livingston of Fairplay, Federick Co. Maryland. I don't have any info. further back than that, but David's wife was Anna Mishler, born in Lancaster PA. I am 6 generations later, my maiden name is Lumadue. On a side note, David's daughter, Eve Livingston married a Henry Foust of York Co. Pa and I have earlier back to the 1700's on his side and those furthest back came form Germany.
