Hello June,
I am pleased the information was of use to you.
It was usual for widows and widowers left with children to remarry quickly in those days. Life had to be practical and both men and women needed a partner to help them. Elizabeth looks to have died as a result of childbirth as you say.
I wondered if you had the census returns for William Rossiter. I found him in those for 1841, 1851 and 1861.
In 1841 he is living in Meare, reference: HO107/943 Book 5.
William Rossiter aged 55, Ag Lab, born Somerset.
Ann Rossiter, aged 53, born Somerset.
William Rossiter, aged 21, born Somerset.
Elizabeth Rossiter, aged 15, born Somerset.
Ambros Rossiter, aged 10, born Somerset.
Maria Rossiter, aged 8, born Somerset.
Eliza Rossiter, aged 7, born Somerset.

William Rossiter head, married, aged 64, occupation Farmer's labourer, born Wedmore.
Ann Rossiter, wife, aged 62, born Wedmore.
Eliza Rossiter, daughter, single, aged 19, born Wedmore.
Dianna Reeves, widow, aged 101, born Wedmore.
In the 1861, the name has been transcribed as Roseter. Reference: RG9/1667 Folio 54 Page 11.
William Roseter, head, married aged 75, Labourer, born Wedmore.

It appears that it is William Rossiter senior who married Ann Reeves.
Jo.
