Hi Mike just looking back at some of my Records, found that Richard's wife is Frances b.1801, so bit confused with Fraurag from the 1841 census unless the writing on the census page is difficult to read?cheers Paul
Add that to the results from the new LDS FamilySearch site and there was a Charles HARRINGTON baptised 27th March 1829 in Kidderminster to a Richard and Sarah HARRINGTON. Changing dates there, you will find other HARRINGTON children there too. There also appears to be an 1818 baptism with a variant name of Elizabeth, making her approximately 20 in the 1841. Perhaps she died or got married.
Looks like the same family to me, perhaps he married Frances later.
