I have the book my maternal grandmother wrote, tracing my grandfather's family, Dickson, back to 1662 in Glasgow (it actually goes one generation farther but has no hard dates, and 1662 is death, birth unknowen).
There is another book she wrote about her family, Bye, but I don't have a copy of that one. Mom does though.
Dad's side hasn't been done, but my paternal grandmother was a Stewart, so I get the Scots from both sides.
