Which Douglas line are you researching? Dates and places help making connections.
I am trying to go back as far as possible with the American Douglasses and would like to contact Scots Douglasses also. I intend the latter because I will be travelling to Scotland in the Spring of 2012.
I subscribe to the view that early Douglases could not spell, and so relied on scribes to record their names. Some used one S, some two. If the father was present, then the spelling would probably be passed on, but if not, then whatever the scribe wrote would do. Apart from the S, there are many variations on how our names are spelt.
On that subject, the battle is usually spelt 'Arkinholm'.
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?
