Once again, thank you for all that information on Scottish marriage, it's extremely interesting, I think they had a good system really.
This is definately the right family, it fits all the information I already have. It seems John Glen was born in about 1817, which is what I had given to me by another source, but wasn't sure about.
The Dunn name is a good clue, as is the middle name of another daughter, Janet Anderson Glen.
My grandfather's name was Hector MacDonald Glen and his daughter's middle name is also MacDonald. I spoke to her the other day and asked her about the name MacDonald, and she has never known were it came from except that it was also her father's middle name.
I will do a bit more searching for the Alexander Glen and Catherine Dunn, I need to write this all out so I know who I'm looking for, it gets a bit complicated.
you're a wealth of information !
