Hi Amyuk,
Have tried to find out about Craigend House without success. There was a Craigend Mill in Kilmarnock but I doubt they got married there!! The only other thing I could think of was Craig House which was outside Kilmarnock. There is a Craigend Road in Troon. Perhaps a look in a street directory for Kilmarnock for 1902 but I haven't had a chance to check with The Dick Institute, Kilmarnock or the Baird Institute, Cumnock. Your other option could be the Ayrshire Archives.
However you may have found out something yourself by now.
Regards
Hollyd
