Which Douglas line are you researching? Dates and places help making connections.
I was researching ancestry on the Morton/Stewart line and found several photos connected to my great great great grandparents. Interested in any information relating to them and in finding living ancestors.
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?
