Come back to this again to see if anything else shows. I'm back full circle to possible parents being a Charles Scott and Margaret Douglas

These parent names come up on on a marriage in Blenheim, Waterloo Ontario:
Archibald Scott, aged 46 b. Scotland. Parents Charles Scott and Margaret Douglas. Married a Jessie Rogers, aged 33 b. Scotland. Marriage date 5 May 1865.
I saw a reference to Blenheim in that link I posted earlier regarding John Scott (I think it was that link that I posted earlier, I looked at a few!).
