In the information above, JASD has and Edward (1821) with a Father, Ralph. I have followed this up on his Tree on GenesReunited and he indeed has a brother called John on there,but I can find no solid information of his, or Edwards birth.
I have found Edward's marriage record which states his parents are Randolphus and Agnes. I have also found Edward living with Ralph and Agnes in the 1841 census. But I just cannot find the last piece of evidence I need, which is his birth or baptism record, or that of any of Ralph and Agnes's children
Other than that, there is a John Moon from 1809 that has a Father, Mathias and Mother Alice.
