Thanks Martin, yes I have that census record on the profile. The allegation by descendants is that her marriage record made her father James, Fishmonger, not Edward, Fishmonger. The only Mary d/o James that I find on the '51 census in the Ely area was born around 1844 so a bit young to have married in 1856, and that James was not a fishmonger, but an Ag. Lab. I have also looked for possible Edward James and James Edward births etc which could explain the confusion, but no luck. Thanks again for taking a look. I guess the only really conclusive solution is to see that marriage record, but I also can't imagine that even the worst handwriting could make Edward look like James!
