Re: alabama 1855 census

I know, but i live in Jackson, MS and our archives does not have it.I need to find William Louis/Lewis Dunn in 1855.In 1850, he is in Jefferson county living with older William Dunn and family.In 1860, he is in Marshall County, AL with 3 children and no wife.I need to know his wife's name, or where he was in 1855.His first child was born about 1854/55.In 1860 he has a baby on the census, so the mother may have died in childbirth.Any clue would be helpful.Thanks,Jo Dunn Sheppard
