Hello john
This is a long shot but it might add up.
Did your George marry Mary Walker in 1844? If so it looks like Stansfield was her home village as there is a Mary Walker born c1826 living in Stansfield in 1841.
I have found a John Potter 55 & Hannah 50 living in Clare in 1841 with sons John 14 & James 12. There is a George Potter 15 living with another family in Hawkedon at the same time.
On Familysearch the bpt of a George Potter is recorded on 30 Jun 1822 in Rede, Suffolk, parents John & Hannah Potter. Rede is just north of Stansfield & Hawkedon is somewhere in between. I also found a Non Conformist record on the same site for James son of John & Hannah 25/9/1829 Clare. Could be the same family - Clare is not that far south of Stansfield.
I found this marriage on the Suffolk Marriage Index
John POTTER m Hannah CANT 24 Apr 1820 Poslingford (just south of Stansfield)
How you prove a link is another matter - were there any children from the short marriage?
