As there is no census return for Baumber 1861 I,ll try a diferent tact. looking for charles marshall born Walcot 1826 ish. his family are all mostly Hemingby where there are other Charle's born around same time. His son George was born sept 1861 in baumber. I do not know which Walcot but guess near Billinghay.On the 1871 census his wife is Jane born 1829 West Ashby.but again can't find a marriage . He is also in Hemingby on the 1871 census.
