Although described as "of South Tawton", Joanna Underhill was baptised at Hennock in 1798, had a child baptised there in 1819 and married there in 1826. Much closer to Kingsteignton.
Is there any way in which it might be possible to identify James Saunders of Kingsteignton more fully or, alternatively, establish how many men of that name were living in that area at that time?
My 3xgreatgrandfather, James Saunders of Kingsteignton was aged aged 21 and single in 1822. Was he the father?
