Hi,
Don't know if you have noticed, but the Hannah who was married to David Minns was probably living in 1841. She is living with a James and Elizabeth Morrison on Cross Lane, St George's Colegate. James Morrison married Elizabeth Minns in Heigham 17 Oct 1806. I can't find a baptism for Elizabeth, but that may be because of Heigham records being incomplete. Hannah has an estimated birth of around 1758. There is a Hannah Marsh baptised in Hellesdon to parents Robert and Hannah Marsh 18 February 1759. A Robert Marsh was married to a Hannah Piggin in Hellesdon 25 Feb 1758. He is a widower and farmer and dies in 1762. Hannah is from Bawburgh. Mary Minns, sister of Robert Marsh Minns (b1776 in Hethersett) was baptised in Bawburgh in 1778 so it makes me think that this could be the right Hannah)
A David Minns aged 84 was buried 13 September 1835 in Heigham, he was resident St Martins at Oak. He could be the David Minns born to John and Elizabeth Minns in Hethersett in 1755 baptised 5 September. A John Minns from Hethersett married an Elizabeth Reynolds from Hethersett on 4 Sep 1736 at St Stephens in Norwich. They had several children thereafter in Hethersett: John, Elizabeth Robert, David Susan/Susanna, Esther/Hester born between 1737 and 1755
I think John Minns is likely to be the child of a John and Susannah Minns. I have not found a baptism for John but there are children, Elizabeth, Robert, David, Esther and Hannah born to them in Wymondham between 1713 and 1723. A Susana Scarling marries a John Minns 14 July 1711, St Stephens, Norwich. Maybe they were not of age and married in the city. They give their parish as Wootton which could either be Woodton in South Norfolk or Wootton near Kings Lynn.
There is an Elizabeth Reynolds born to a Robert and Mary Reynolds in Hackford near Wymondham, baptised 15 September 1717 This is not so far from Hethersett. As she would not be of age it may be a reason why they've got married in the city. Hope this is of some help.
