Hi! Many thanks for your replies!
I have checked for Maycock marriages and cannot find any to a lady called Elizabeth.
George Sykes was baptised at Wollaston on 18th November 1704 and i believe died at Wollaston on 20th August 1786. He was the son of a Robert Sykes and his wife Katherine who were married at Wollaston.
His wife Elizabeth died on 7th January 1777 also at Wollaston.
They had the following children:
Katherine, Ann, John, James, Mary, Anne, William, Mary, Elizabeth and Eilzabeth.
I think the Elizabeth Meacock baptised at Marston ST Laurence may have been the daughter of a John and Sarah Meacock but not sure!
Thank you!
