Welcome to Rootschat!
The mother's maiden name given for the birth reg of Elizabeth in sept qtr 1932 is Thomas, not Rodriguez.
Marriage reg
Thomas G Davies march qtr 1919 Gower vol 11a pg 1609 to Elizabeth E Thomas
possible death of mother
Elizabeth E Davies 47 dec qtr 1940 West Glam vol 11a pg 1646
The second marriage is to a Rodriguez
Thomas G Davies dec qtr 1942 vol 11a pg 2237 West Glamorgan to Mary Rodriguez
I won't post the names of Elizabeth's siblings in case they are still alive. But if you search on FreeBmd for births with surname davies and mother's maiden name Thomas registration district Gower , there are several possibles.
Buying the marriage cert for the parents would give you the names & occupations of their fathers, their ages & possibly their address at time of marriage which would help to trace them on 1901 census.
