The convict records of my gg grandfather Henry BAVIS or BEVIS shows that he born at Bath Somerset about 1825, tried at Bridgwater SOM in 1849, convicted and transported to TAS in 1852. His father was probably Peter BEAVIS.
Maybe are not researching this particular family but you may know someonewho is. Hoping to hear from you soon. John Bevis in Geilston Bay TAS
