I have a very long Ainslie lineage starting in Scotland before 1200 AD. My ancestor, Hew Ainslie and his wife, Janet Ainslie, (they were 1st cousins) came to Louisville, Kentucky, USA. I can send you the info. I have if you would like. Most of the info. comes from an old manuscript which I have since framed (but first, I entered the data into my computer).
Please e-mail me if you would like some extra information. I would love to share.
