Hello... I know you put your message up quite some considerable time ago and may already have the information but thought I'd let you know I have an Andrew Mowatt (1804), Married to Ann Middleton on 31 Dec 1842. She is his SECOND wife, his first wife being Elizabeth Low. I have a copy of Andrew's Death Certificate which lists these two marriages and his parents are listed as John Mowatt and Jane Henderson. I think someone has already given you the name Jean Henderson, but I believe these names were often inter-changed, so I think we're on the right track. I hope this has been helpful.
