Benjamin and Mary were married Dowland(Iddesleigh), 19th March 1734.
Other children baptised there include Richard 11743, William 1749 Mary born 1751 died 1765 of Winkleigh/Winkley, and Wilmot born 1745.
Have looked on family search, if you find an entry with a camera alongside you can click on it and see the bishops transcripts, and go back page by page,
could not find baptism of Benjamin, wondering if he was baptised at all? or perhaps as Rix, if the date of death and age are correct?
