Which Douglas line are you researching? Dates and places help making connections.

There is a fairly strong Douglas connection with South Africa, but, sadly, I do not have much on it here in the Douglas Archives.
If you search for south Africa in the History section (using the box bottom left) and in the Genealogy section (use the drop down Find menu, and search in births and deaths), you will find some results, which may help.
I would love to be able to include more, si if you or anyone else can contribute, that would be good.
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?
