Bit of a jump around the Amesbury records for this...............
As expected the 1832 marriage record gave no details of fathers for William Eyres and Jane Benger.
In 1849 they did - 19 Jul 1849 marriage of Philip Eyres, widower, son of Robert Eyres and Jane Eyres, widow, daughter of John Benger.
Unable to find an Amesbury baptism for Philip, which was no big deal, but there was a baptism 3 Jan 1802 William Eyres, son of William and Mary Eyres. This was slightly earlier than thought but a burial record 29 Apr 1847 William Eyres, age 45, confirmed it.
Philip and William would appear not to be brothers but possibly cousins as these baptisms tend to suggest
20 May 1758 Robert Eyres, son of Robert and Elizabeth
25 May 1765 William Eyres, son of Robert and Elizabeth
2 Jan 1763 Philip Eyres, son of Robert and Elizabeth
It seems very neat but on second thoughts they could be a bit early.
