Hi Annie...the marriage is correct. There were only ever 3 things that we had to go on. Firstly, my grandparents marriage certificate(which is what you found) and on that he states his father as Hector, big question mark there) on that he states his age as 21. Secondly, we had a photo of a group of seamen, with a cross mark above one of them, which is supposed to be my grandfather, then from that, we could see he served on the Prince of Wales in the Royal Navy, so that then led me to contacting the M.O.D, who sent me a few details of a John Mackay, but it was the last one that proved it was him, because it showed he had jumped ship in 1918, which is what the family knew about him. At the time of my grandfathers desertion, my father was only 4 months old, so he never knew his father, so then he was unable to tell me anything other than the knowledge of my grandfathers desertion.
If the John Paterson is really him, we deduced that he had gone back to the original birth surname, due to his desertion, and yes, this one married Elizabeth Boyle in 1925. John,s mothers maiden name was Mackay, which she reverted to after she and Alan had divorced, because he went on to marry someone else. We seem to think my grandfather chose to use his mothers name when he married Irene, my grandmother. Its a heck of an entanglement, is,nt it..........regards Mary Elaine
