Well, Ann died in 1838 and was the wife of Benjamin, a stonemason.
Benjamin stonemason died 1839, given age 70 so yob 1769 (ish!) He died in the union house. But Ann, his wife, died at Chesterfield Road, which is where William and his family lived, so what with that and William also being a stonemason, it's a good bet that this Benjamin and Ann were William's parents.
But which couple were they? There are no baptisms to Benjamin and Mary, all the relevant baptisms have Ann as the mother's name.
So in summary it seems that ONE Benjamin married Ann Wilcock in 1795, and they were the parents of Mary, Ann and Hannah.
The OTHER Benjamin, having been widowed, married Ann Wordsworth in 1799.
Either couple could then be the parents of Anna (1801) and William (1803). Frustratingly no father's occupation is given on my cd for any of these children at baptism.
Ann's age was given as 80 when she died in 1838, and stonemason Benjamin was 70 the following year. So her yob might have been around 1758, making her quite old in reproductive terms when she married Benjamin in either 1795 or 1799. Not too old to have children, but perfectly old enough to have been married previously - and I can't see a baptism for either Ann (Wilcock or Wordsworth) in Mansfield (although of course she may have come from elsewhere).
If you want to try to trace any of the children of either couple, just in case it offers any further clues, these are possible marriages at Mansfield:
1818 11 24 Thomas COUSINS Mary ARMSTRONG
1824 09 14 James WILSON Hannah ARMSTRONG
What I CAN'T see in Mansfield is a marriage or burial for Ann Armstrong b 1797, or a burial for Ann the wife of the ag lab Benjamin.
