I recently read you post where you indicate Alexanders parents were.John Stewart and Janet Murray and that you recieved that information from Scotland. What sort of information did you receive? After reading this post i did some research and found the following website:http://www.electricscotland.com/history/nation/blantyre.htm
I thought I was on the right track until read the following excerpt from that document:
" Sir John Stuart’s son, Sir Robert Stuart of Minto, married Janet Murray, of the house of Touchadam and Polmaise. He had four sons; Sir John, his heir; Walter; Robert, prior of Whithorn; and Malcolm, and a daughter."
I am in no way discounting your discovery but was hoping you could provide some references or perhaps a copy of what you received.
