Thank you Coco and Trish, that information looks promising so far.
Coco, I agree that finding the marriage of Hannah Matthews and Moses Cryer would be key to establishing a link to the Stanton Fitzwarren Matthews family - can anyone find it? It would be really helpful if I could establish who her parents were. The only things I know for sure about "my" Hannah are that she was born around 1809 (not in Gloucestershire) -she died in 1867 age 58, she married Moses Cryer in about 1837, she had a brother called Charles, and Hannah and Charles were both in Wellington NZ in 1849.
A couple of possible connections -the Charles who was in Wellington was a shoemaker which matches the 1841 census. And I notice that the names of Henry and Ann's children are very similar to the names of Moses and Hannah's children - Ann, Mary, Jane, Hannah, and Charles are all common to both families.
I'm interested to see the name Hall, because it has come up a couple of times in connection to the Cryer family. Some family trees have a son of Moses and Hannah called Charles HALL Cryer, b. 1845 in Lechlade, Gloucestershire. Other trees have him just as Charles Cryer - can anyone find a birth record for him which would verify the Hall part of his name? Also a Charles Hall (not born in county), age 15, was with the Cryers in Lechlade in 1841.
