It’s a very long shot but I have found an Arthur S Bland who was born in about 1880 in Chatham, Kent. He was the son of George Bland, born about 1856 in Capston, Kent, and his wife Sarah who was born about 1852 in Aylesford, Kent. They were all living at 232 Luton Road, Chatham in 1881. In those days Chatham and Gillingham were small towns and Capston was an adjoining village. Nowadays they are really all combined in one urban sprawl. Unfortunately I don’t have a Croucher family in Gillingham in 1881 that might turn out to be the parents of May Harriet, as the ages are wrong for a birth around 1890.
If you glean any more information on her at all just give me a shout and I’ll see what I can find for you.
