1860 and 1900 censuses

[Talmage]

I'm looking for the following:
1860 census:
Thomas Marchant, born 1835, Sussex, England
Anne Marchant, born England, date unknown
Lillian Marchant, born New York, 1858 or 1859

1900 census:
Thomas Marchant  (as above)
Caroline Marchant, born Massachussetts about 1839

I know that Thomas was working at the Green-Wood Cemetery, New York from about 1860 until he died in 1904.
I cannot find them in these censuses or the immigration records on Ancestry although I have for the 1870 and 1880 censuses.
Any help very much appreciated.
