Hi Greendoor,
Trouble with the surname of Doherty is that we cannot use the Soundex as SP will use Doherty. If we want to include the Docherty, it still do not work using the Soundex.
That means we have to use two surnames in order to find her birth entry.
Interestingly, it bothers me a bit--that she got married in Campeltown which is quite a distance from Glasgow.
Wondering if you can send for the church record on their marriage?? It may tell us if she was of the parish or not.
Also, you would need to tell us the names of the witnesses on both marriage certificates so we can try to tie up any loose ties. Also, what was the occupation of her father on both certificates.
Interestingly, there was a Marjory Docherty in 1901 but she was 80 years old and in Ayr--not far from Glasgow.
There was a 1886 birth entry for a Margaret Doherty in Ayr.
And other in Glasgow...
I am tempted to take a peek at one of the entries.
Any brilliant idea that we can go and find her...otherwise, we chalk it up as a mysterious chapter in your Grandmother's family history.
