This is complicated! I will have to think about the families for a wee while. I think my ancestor may be related to Samuel Brown, via the two Campbell brothers that I know of. Trouble is, on the OPRs only the father's name is given in some cases.
What my grandmother said was that "the lady who was aunt to Robert Burns' family was also aunt to our family" (that is the Campbells of Ayr).
I have an ancestor Thomas Campbell, can't find his marriage but his daughter was born 1766 in Monkton. The family were later in St Quivox, but wait for it, it was the same place, only the parish boundary moved.
I intend to devour the Kirkoswald OPR, I'd just love if I could buy a copy and do it at home.
I don't know of a connection with Ochiltree, but who knows?
I don't know how far out your birth dates are compared to what's on the records, but I wouldn't be too worried about that. People told porkies about their birth dates all the time, and sometimes it's a christening some time after the birth which is recorded. Two brothers may well be christened on the same day which makes them look like twins, but there could be years between them.
One thing which interests me is the similarity between the Christian names in your family and mine at that time - that can be a clue.
I wonder where you are researching from - I'm in Scotland.
Thanks for your reply, I'll look at your postings and see if I can work anything out.
