Now you see why I'm having fun with this one.
Sorry about the wrong year of the marriage what it should say is Edith Scholes( my mat. Gran) was born 13/Oct/1886 at Huddersfield.
When I got her marriage certificate it has father's name as George Scholes but she is down as Edith Rusby Scholes and that is how she signed the register.
I thought great mother's maiden made-- I can trace that line now

how daft can you get thinking it could be that easy.
Looking on FreeBMD I found the marriage for George Scholes and Ellen Rusby in 1888 Thorne.
On the 1891 census they were found at Thorne and we have George and Ellen, then there is Edith down as step/dau age 4 years. I don't know what her surname was down as but on the 1901 census was Edith Scholes and still living at home.
She married my grandfather in 1906 in Thorne.
I can see this may mean a day at the archives. Can anyone tell me where the archives are and if it's easies to park there or do the last leg by bus?
Thanks for all the help, Anne.
