James was born in Hawkchurch and Sarah in Whitchurch Canonicorum, Dorset. They married at Bradpole but lived in Hawkchurch, where the first six children were born. James was a labourer. Even though their marriage record shows James a bachelor, other records indicate James had previously married Sarah's sister Mary. A Mary Norman was born to Robert & Mary (Sarah's parents' names) at Bettiscombe in 1806 and a Mary Stokes was buried there in 1833 (aged 27).
In 1841 James & Sarah were living in Hawkchurch - Sarah's mother, Mary Norman, was then living with them.

The ancestry of Robert Norman and Mary Mullet can't be positively verified from records found, with alternative baptisms found for both. However, the ancestry shown is considered most likely when considering such things as baptism locations etc.

John and Hannah were both born in Hawkchurch, where they married.

Could Robert be the son of Robert NORMAN and Mary COSINS, born/baptised in 1781 at Whitchurch Canonicorum?
Mary's age on the 1841 census was given as 60 - born 1781?. Her burial record (1847) gives her age as 72 - born 1775?
Could she then be the Mary Mullett, baptised 1779 at Burstock (a few km NE of Bettiscombe) - father Francis.
