Hi Whiteout
Thank you for the reply.
I searched IGI and found a "Ketheren" Dishingtoun marrying a Thomas Carstairs in 1723 as Steve Wakely claimed, although in Kingsbarns. I emailed him and he said that he got his details on the Carstairs family from another person, a Fergus Smith who has an extensive website documenting Carstairs couples. I also found the marriage between a Thomas Carstairs and a Margaret Carstairs for 1741 in Kilconquhar:
https://familysearch.org/ark:/61903/1:1:XTPL-4QTSteve's tree showed no children for this second marriage, here's a link to it:
http://www.stevewakely.com/wc05/wc05_354.htmThere are 8 children shown for the first marriage to Dishingtoun.
Here's the link to Christian Bruce and Thomas Carstairs marriage:
https://familysearch.org/ark:/61903/1:1:XTPL-4QWIts in 1733, although a different record transcribes it as "1743" which is clearly an error since their first child together was born in 1734 in Kilconquhar.
I'm not sure that the Kingsbarns "Thomas Carstairs" is the same as the one marrying Margaret in Kilconquhar as Steve and Fergus clearly thought.
As for Thomas Carstairs who married Christian Bruce in 1733, he cannot be married to her and have had children with her well into 1750 and also have married Margaret in 1741. Could they have been relatives, though? Kilconquhar is a small place after all. I am confused...I need to try and figure out if my Thomas really is the son of David Carstairs of Kilconquhar and Elspeth Todd born in 1707 as other trees hold. Steve and Fergus seem to infer that the Thomas C marrying Margaret C in 1741 is the 1707 Thomas but how can I be certain that it isn't mine since he was married in Kilconquhar even earlier than the former?
BTW I made a typo in my first post. It was Christian Bruce, his wife, who died in 1788. I don't know when Thomas died.
