Hi Sandra, I am not sure on anything I have found. I have only searched and found this info on the LDS site. I can't seem to find a 51 and 71 census either. I started searching on James the grandson, however I cannot be sure that this person is the same as who married Frances. What I did notice in their marriage was his mother being Jane and no father! Same with the Jane marrying Edwin, only link is father as James! Would need to contact Fletcher family for verification I guess. Certainly nothing concrete, just rambling research, but I figure I had to start somewhere. Getting back to Jane the daughter of Thomas missing in 1851, it's almost like she may have gone back to Ireland or into Scotland perhaps!? I don't know. I can't access the 1851 or 1871 census. I am not sure if I posted to the Fidler and Fletcher sites as I type this, they may be of assistance to us.Sorry very amateurish at this whole research thing! Which is probably very annoying to others!
