Samuel Benjamin Stannard

I have followed Samuel Benjamin Stannard (b: 1829 d: 1884) from Missouri to Connecticut.In the 1850 census of Clinton, Middlesex, Connecticut I found Samuel B. living with his mother and siblings.But evidently the mother, Roxanna Stannard, was widowed.She is the head of house and 54 years of age.Does anyone know of this family?What was Roxanna's maiden name?What was Roxanna's husband's name?Thanks.
