His first spouse was Mary Anne Raynsford (1795-1831), by whom he had one daughter named Emma.
His third spouse was Emily Jane Wilkinson (1826-1898), by whom he had three children.
Violet Frances Russell was born to him (according to her marriage records) about 1843.. Her half siblings from Emily were born in the 1860's. Hence, if Charles Dupre Russell was the father of the bride at the ceremony in St. Martin, Jersey, then he must have had another wife.
I suspect Charles D. Russell is connected to the Dupre family connected to the Earls of Caledon, but parents sometimes name their children after famous people.
