I am not clear whose child she was.  All we know is that she was named as a granddaughter of Margaret Ann Leversage and that she appears in a boarding house in 1891 in the company of other young daughters who had been born abroad and whose parents were possibly abroad again.  Not unfairly some have read her name on the 1991 census as Leversodge.  Dora has no birth record that I have found on either Ancestry or FindMyPast.

It looks like she married in 1906.
