Hi Michael,
Williams first child, James, was baptised in Tynemouth in Christ Church on 13th nov. 1836. I havent been able to find a baptism record for their second child yet, Mary Ann. But believe she was born in Amble, Northumberland. Their last two children that i know about were both born in Warkworth according to the census records i have for them. Again, i dont have any baptism records for either.
From the census records, it seems that William and Dorothy moved around tynemouth quite a bit as each census has them living in a different area.
1841: residence in warkworth
1851: residence in Amble
1861: residence in Tynemouth
1871: residence in north shields.
As for looking up william in the parish records for berwick... i havent been able to find any online. I dont know what parish he was from, or what church.
Unfortunately i dont have any means to get hold of the records either. I was hoping that someone on here might be able to help me if at all possible?
