Hi, are you sure about them marrying in Glasgow? I ask as I checked Scottish records and cannot find a reference to Abraham and Mary's marriage anywhere.The only reference to an Abraham I found was in the Ireland Tithe Applotment books in 1824 at St John's,Magerraboy,co Sligo. There was this from the census:
1861 Scotland census:
Abraham Fantan age 31 occ:stableman born:England Mary Ann Fantan age 28 wife born:Renfrewshire,Johnstone Elizabeth Fantan age 8 daughter born:England Thomas Fantan age 6 son born:England Janet Fantan age 3 daughter born:England Alice Fantan age 1 daughter born: Glasgow
Is it possible they may have wed in England??
I did find this in the free BMD indexes;
September 1852 Manchester,Lancashire,England groom:Abraham Fenton bride:Mary Ann Johnson
I believe this to be the people you seek.Hope this helps,Kim
