Which Douglas line are you researching? Dates and places help making connections.
I am not sure, My grandmother used to comment about the black douglasses. I know that they had to change their name to Drysdale as a result of the king of the time. I have name but not what actual lines.
My most recent Douglas ancestor is Mary "Polly" Douglas (b. abt. 1794 in Tennessee), daughter of Joseph & Margaret Douglas. Polly married William Fears in Grainger County, TN in 1809. Thanks for the greeting.
The more information you can give about the people you mention, the more chance there is of someone else connecting with your family.
Dates and places of births, deaths and marriages all help to place families.
Professions also help.
'My great-grandmother mother was a Douglas from Montrose' does not give many clues to follow up! But a bit of flesh on the bones makes further research possible. But if we are told who she married, what his profession was and where the children were baptised, then we can get to work.
Maybe it is time to update the information in your profile?
