Hi Harriot -
This is a long shot, but Sharp in Scotland can also be spelled Shairp. That is my family tree, and Janet Shairp is a common name in that family - I found four of them but unfortunately, I don't have dates or spouses for them. Most of the names I got off Sasines and they were all daughters, wives, or sisters of various Thomas Shairps of Houston in Uphall. Just another direction to look that might help.
Cheers - Arcona
