I've hit a dead end with this family - the last record I can find of them is in the 1881 census.
William
Marchant (b. approx 1835 in Thursley,
Surrey) married Mary Ann Donmall (b. 1835 in Chislehurst, Kent)
They had 4 sons - Joseph (b. 1865), William (b. 1868), James (b. 1871) and Henry (b. 1874)
Anyone out there have a connection?
