No Rose Without a Thorn
Rose Fox applied for a separation summons against her husband, James Thomas Fox, a bricklayer
of Westbourne-grove, Bexley Heath. Her husband, she said, assaulted her on Monday and Tuesday.
The application was granted.
In 1921 and 1939, she still lists herself as married, so no formal divorce occurred perhaps.
