Margherita was born very late in 1882 or the beginning of 1883. [1]
20 Mar 2021 - Using FreeBMD - unable to find a marriage between Mr Murphy and Miss Kinross. Possibly married in Scotland?
Quite likely that Hilda and Margherita were twins, but no Census returns on FamilySearch to prove or disprove. Also, neither girl appears again in FreeBMD, so probably did not remain in England or Wales. MURPHY, MARGHERITA VIOLETTA Mother's Maiden Surname: KINROSS GRO Reference: 1883 M Quarter in WOOLWICH Volume 01D Page 1215 also MURPHY, HILDA BEATRICE Mother's Maiden Surname: KINROSS GRO Reference: 1883 M Quarter in WOOLWICH Volume 01D Page 1215
21 Mar 2021 - Ancestry has a family tree with Margaret Violet Murphy, mother's maiden name Kinross, but has her birth as Nov 1883 - not possible as Margherita's birth was registered in the first Quarter of 1883. This family tree does have the parent's marriage in Scotland.
