I have a Mary Ann Bartlett, born Brixham who married Francis Challis of Ramsgate in 1845. Mary's father was Peter Bartlett, mariner. There was a large migration of Brixham fishermen to Ramsgate and Dover around this time. I would guess that Mary Bartlett's father would have been born c1810 so it looks very promising to me. Pease contact me for more details.
