I have now found her parents on 1891 census John and Mary Williams in Canton Cardiff
John 47 from Brecon and Mary35 from St Ives Cornwall . with sons Albert 16 and Frederick 5 both b Ashwater? Devon and David 5 b Cardiff.
Alma Jane is 2yrs old .
We also know from family info that she had a sister Mary also with her in the Workhouse School who later in life lived in the Rhondda valley
Need to go to Glamorgan Records office next re Workhouse School to get more facts
