There is a Frederick Charles Foot born in Wimborne in Sep 1890 (5a 253). The co-incidence of names and places seems to suggest a connection.
In 1901 this Frederick was living with his family in Bournemouth (RG13/1042).
In Jun 1910 a Frederick Charles Foote married in Christchurch either Mary Elizabeth Warren or Daisy Ellen A Bell. Neither, of course, is called D'Silva, which may mean that...
..in 1901 Frederick is calling himself: Charles Foote, 21, living with Alfred, 58; Alice, 45 ,and Harry, 17 (ie the right family) in Bournemouth/Christchurch.
A Frederick Foot married in Jun 1911 in Southampton and one of the possible wives is missing, but I can't find a D'Silva with a similar reference.
