1865 Born (from census age) . However if she was born Ballincollig , then I think she is Julia Sullivan , Birth Date: 26 Jun 1867, Birth Place: Ballincollig, Cork, Ireland,, Father's name: James Sullivan Mother's name: Elizabeth Caughlan ,FHL Film Number: 101154. In which case she would have been 15 when she married. This would not have been abnormal in Ireland at that time
1883 Feb 4. ,The date of the marriage in Ballincollig given on Edward Corringham (Mannock)'s service record.
1891 census in London
She moved to India with the family some time after her husmabd was posted there (11 Spe 1897 is the date of the posting of her husband) Various books indicate that the family followed after that date, probably in 1898, returning to UK in 1902)
1903 Nov 3.Edward Mannock senior, her husband, was discharged from the British Army in Canterbury, he was discharged at the expiry of his service, and within weeks he deserted the family, taking with him their meager savings. None of them saw him again.
ODNB says about the brothers' pre war employment: The desertion of Mannock's father left his family in great poverty, and it was necessary for Edward to earn a living, which he did as a greengrocer's (and then a barber's) assistant, before joining his elder brother Patrick in working for the National Telephone Company. Three years' office work were followed, more congenially, in the spring of 1911 by a transfer to a line gang. This entailed a move from Canterbury to Wellingborough, Northamptonshire, where Mannock widened his circle of friends and articulated the social and political opinions that he was to hold until his death—a passionate combination of socialism and patriotism.
She had 4 children in India for about 4 years from 1898. My present belief is that one daughter was born in India and is in the photo above. Logic leads one to assume that she was born 1899/1900, The daughter born in 1889, Helena remained in Ireland was an uncle and aunt.
