My GGGG Grandad was John Gibson who married Isabella Mackie.
His son John is my GGG Grandad who was born on 18/6/1818 and died on 11/9/1876 in Cortiecram, Lonmay.
He married Jean Davie on 23/7/1843 and the had 7 children, one of whom was George who was my Mum's Great Grandad.
George married Charlotte Pratt on 4/5/1867 and had 4 children with her but tragically she died in 1874 after the birth of their 4th child(she was only 26).
As you rightly said George then married Mary Yule on 14/12/1877 in Old Deer and they had 6 children.
I presume that you know they are buried in Aberdour(Plot 243).
If you want any more information I'd be happy to oblige.
What relation are the Gibson's to you?
