Gosh!
I have definitely come across these families before, possibly helping someone else on this or another forum?
I cannot remember where but I do recall that Arran seems to be the home of the McKillops .
I recall looking at marriages and births on FS and could see numerous McKillops, men called Archibald!
Also that McKillops on the 1841 census on Arran were numerous
I will try and remember where, when, and for whom that I looked at this before.
Edit:
I knew that I'd seen the McKillops before.
I had been helping someone at the end of last year, re a McKillop family of Kilmory.
On that occasion, I was trying to separate 2 women, both called Flora McKillop both born in Kilmory.
I found marriages for both women, and I could not separate them from each other.
One remained in Scotland whilst the other emigrated to Canada.
I left it up to the person to obtain the Scottish death cert for his Flora McKillop to ascertain the correct parents
Neither girls were born to the couple on this thread, but both had brothers named Archibald McKillop!
