Now have the death certificate. She is Minnie Frances Hill,. otherwise Loring-Fox, widow of Reginald Thomas Hill, architect, died May 1942. I assume he is the Reginald Hill mentioned in earlier posts, though working for a builder on 1901/1911 censuses, though could have bettered himself later. Be interesting to see the family on 1921 census when it appears.
Minnie was his second wife, the first being the former Minnie Berry who died in 1902, the second being Minnie Frances Lamb, born Cosford, Suffolk, 3rd quarter 1879, who married Hill in 1904. I am assuming all this as no other suspects.
The family is on 1911 census, but none of the children are born 1904/1908, the possible main birth dates of E. A. Loring. Wonder where the name came from as it does not appear to be connected to anyone else in the family. There is a family tree for Hill, but it is a bit of a mess with the children because of Hill marrying two Minnies.
Elizabeth Loring is divorced on 1939 Register, but nothing in the National Archive Divorce archive, nor for Gladys Harriett (Hill) if she had married. That 1962 electoral roll entry for Elizabeth Loring and Gertrude Hill is interesting as Gertrude was one of Hill's daughters by his first wife.
I presume Minnie Loring-Fox is a surname based on her daughter's and Fox, whatever his name was, who was her partner out of wedlock.
