I keep looking at Joseph Sage who married Frances Hogdon in 1810. Frances would have been about 30-34 according to 1851/61 census ages (he was a lot younger). They both say they were b in St Phillip's and were living there for the censuses (she is listed as Fanny). I can only find the bap for one child, Joseph in 1813. I'm surprised there were apparently no more.
That's not especially helpful, is it!!
