As Dathai said, a lot of work needs to be done in Wales and possibly England too.
You need to start with the 1911 census.
Look at all her neighbours, see are any of them possibly related.
Look to see if she is possibly on the 1901 census ~ I have given options for her on our 1901 Census but that's not to say that it's her.
Look on the Welsh, English census to see if you can see her family.
Don't get hung up on the variants of her name; it's one of those nightmare Christian names that has a HUGE amount of possibilities ~ check with C AND K as the starting letter on each one too.
Do you know who your Dad's Godparent's were ?
Might be leads there !
Who were her witness' at her marriage ?
Might be leads there !
