Many thanks for your response. Here are the details:
David KIRKPATRICK b abt 1783 - birth date calculated from his age at death, in Cheshire in 1837.
He married in 1818 to Mary SILLERS/SELLERS in Liverpool, at which time he was a Mariner. With her they had 8 children, all born Caldy, Cheshire, all taken across the Mersey to a Universalist (non Conformist) Chapel to be baptised.
David KIRKPATRICK died when living at 130 Park Lane, Liverpool, a Surgeon.
Mary was a Teacher.
I've drawn a blank in looking for Mariner or Surgeon records - he could have just been a barber, as they were then.
My quest is to take his line back, to find parents, and I've not wanted to assume anything, of course. However, one of his children gave me a clue and ended the latter part of his life in Scotland.
I was hoping that I might get some clues but I realise its a tall order.
Thanks
