Not sure what else to try as I can't get a marriage cert until I can have a rough guess at when and where.
Yes, Freecen is patchy
But on the other hand Elizabeth appears to have been an habitual fibber - none of the info she gives anywhere on census returns etc seems to match up - its as if she enjoyed fun confusing authority so I may well be looking for her with out the real info anyway...
I do have a theory that she may have been an underage run-away and therefore did not want to give her real identity
Or perhaps Thomas was still married to someone else and therefore would/could not marry Elizabeth - he is at least 10 years her senior... so who knows. The cold trails at every turn do seem to hint at some intrigue somewhere along the line.
She marks John's birth cert with an X so was seemingly illiterate.
I may never find out who she or Thomas were I suppose.
