Researching the family of Nellie May Keen (I am connected via a sibling's descendants).
Birth
14 05 1894 - 89 Cornwallis Road, Islington, London, UK
Marriage
13 10 1912 - St Marks Church, Islington, London, UK
Death
15 03 1930 - Elizabeth Garrett Anderson Hospital, St Pancras, London, UK
Found the birth records for two children:
1. Harry William Webster
22 10 1912 - Islington, London, England
2. Reginald Harry Webster
02 12 1913 - Islington, London, England
HW's date of birth matches that recorded in a baptism document.
But there is a "British Army WW1 Pension Records 1914-1920" document that says HW's birth date to be 13 06 1909...
