I am trying to find what happened to Samuel Richards after 1861 when he and his family on the census at Forest Estate in Illogan:
Samuel Richards (Head) 25 1836 Male Coowace Cornwall England
Priscilla Richards (Wife) 29 1832 Female Illogan Cornwall England
Samuel C Richards (Son) 3 1858 Male Illogan Cornwall England
Priscilla J Richards (Daughter) 2 1859 Female Illogan Cornwall England
Augusta E Richards (Daughter) 9/12 1860 Female Illogan Cornwall England
I haven't been able to track down Samuel's death - on the 1871 census his family are still in the same place, but he isn't there. His wife Priscilla, is shown as married rather than as a widow, although this could be a mistake: Priscilla Richards (Head) 39 1832 Female Illogan Cornwall England
Samuel C Richards (Son) 13 1858 Male Illogan Cornwall England
Priscilla G Richards (Daughter) 12 1859 Female Illogan Cornwall England
Agusta E Richards (Daughter) 10 1861 Female Illogan Cornwall England
Bessie A Richards (Daughter) 8 1863 Female Wendron Cornwall England
Thomas W H Richards (Son) 5 1866 Male Illogan Cornwall England
I can't find any of the family on the 1881 census, and the next time they show up, Priscilla is in London (and now a widow) with Thomas and her daughter Priscilla Jane is married and visiting Portsea in Hants and Samuel C is also married and living in London.
Samuel C married in 1888, and his father shows as deceased on the marriage certificate.
I'd really appreciate any help in tracking down what happened to Samuel, and what happened to the family between the 1871 and 1891 censuses.
Thank you for any pointers or help you can give
