Hi Marilyn ...
Do you have Ellen's 1884 birth certificate, as this will confirm the names of her parents?
The only Henry TOWERTON (this one with the middle name of Charles) that I can find on the GRO indexes married an Ellen Sarah SWAIN in 1886 in Bradfield RD (covers Berkshire, Hampshire and Buckinghamshire).
There is an Eliza Ellen ATTRYDE on the indexes, but she married back in 1847, and not to a TOWERTON!
Once you have confirmed Ellen's parents' names, then you can search for their marriage, and this certificate will in turn confirm the names/occupations of their respective parents.
