Thank you Northerngirl! I have in fact seen the data base you referred me to, but appreciate your input. I have come acoss your Shaws many times, and have wondered whether my Isabella was closely related, or only distantly? I haven't done much work on the Shaws, simply because the McMurrays have kept me busy for four years now! That and the fact that Isabella's parents are recorded as having been Nathan Shaw and Isabella Mclean. No Nathan's anywhere except for a Nathan McMurray, bell hanger in Gatehouse of Fleet, who seems to have come from Stranraer and not apparently directly related. But who knows? - our earliest known McMurrie (another James) was in Anwoth late 1700's ....along with the Shaws. Have you seen the Isabella Shaw (from Balmaclellan) Will on SP? Its the right area for your Shaws ....
and I'll keep an eye open for them now that I know that you are looking. I have also just discovered, with help from Callywoods (who is a distant cousin from GH of Fleet), that James McMurray appears in the 1841 census in Tongland, age 15! So he didn't die young ....well, it appears not before 1841. Do you know how I can send you my email address without sharing it with the world?!
