Hi Margaret & Ricky,
Had another thought on this.....so look out

Since Annie was born Dec Q 1872 she would have given her age as 28 on 1901.
So I had a look at all the Annie's born in Aberdare aged 28, there are 11.
Discounted 4, either single or still living with parent.
That leaves
Cook, Davies, Jones x3, Owen, Shea, and Thomas.
Tried looking for a marriage that would match between 1891-1901 but can't find one

Will try again this evening.
After that I need a rest
