A baptism entry St Michaels Church Alnwick Northumberland for a John George Kirk 1801 against parents George Kirk and Frances (nee Dudney) it gave Shell Edge Yorkshire and Dublin Ireland.
Several of the Kirk family left Sheffield for Northumberland and then some returned to Sheffield
I have a Marriage for George and Frances c 1779 at Northumberland which haven't been able to confirm, no record at Alnwick. Both George and Frances worked at Alnwick Castle from about 1779 to early 1800's.
Apppreciate all your comments, looking forward to solving this mystery with the help of rootschatters.
