There is proof of the Hamiltons being active in Drumbeg in Ros davies, the TABs 1823-1837 and later Griffiths 1863, see below which suggests he could be part of a Drumbeg Hamilton line. If he was not a Drumbeg native but a Hamilton from Ballywalter was visiting with his wife native for some reason that they are related . the solution would be a church baptism record ie the proof of your notes
Another thought that something happened at Ballywalter and he inherited a farm in Ballywalter already being perhaps related back to a grandfather etc
He would have been about 47 in 1830 with an established family his father speculation a James or more speculation a Brother James
