Hi Elaine,
Here is an entry from the 1841 census showing a Hilder family in Bilsington:
ref HO107 477-5 folio 9, Bilsington
Edward Hilder age 45 farmer
Amy do age 40
Thomas do age 16
Henry do age 2
Ellen do age 17
Harriott do age 5
(Henry and Harriott born in county, the rest not born in county)
It fits nicely with Henry for age and place of birth, but Edward is missing, and at the age of eight, he should still have been with his family. There are no other Hilder families shown in Bilsington on the 1841.
