who did she marry and where? Who were the witnesses? What address is given on the 1903 marriage? It may help to trace her, so the more info you give, the more likely we are to be able to trace her.
Where was she living when her mother died?
Given that she was in Henllys in 1901, there's this possible from 1891, Henllys & Ysgubor y Coed both being in the parish of Llanfihangel Genau'r Glyn
Pentrebach, Ysgubor y Coed, Cards RG12/4586 folio 4 pg 1
Thomas Jones head 53 labourer b. Sguborycoed (deaf & dumb)
Elizabeth wife 63 b. Llanfihangel
Elizabeth J Williams granddau 6 b. Merionethshire, Parish of Dolgelley
I can find Thomas & Elizabeth in 1881
Pentrebach RG11/5477 folio 7 pg 7
Thomas Jones head mar 44 shoemaker deaf & dumb
Elizabeth wife 55
Edwin R son 8
all born Cardiganshire
& Thomas in 1861 is unmarried and living with his mother RG9/4239 folio 5 pg 3, but I haven't found them in 1871 as yet to see if they have other children or if they are married by that stage. It could be that Elizabeth brought a daughter to the marriage who then was the mother of Elizabeth Jane.
