I received your message about Archibald's second wife being Nancy Ann Wilson. However, you have given me no clue as to which Archibald that might be. Archibald is almost as common as William as a Douglas first name!
The more details you provide, the easier it is for other family members to make connections and share information.
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?
