Hi David I, like yourself am descended from Joseph Hornsby and Elizabeth Green. My Hornsby's also came from S.A. The line to which I belong is from Henry and Sarah (resided in Bunbury Western Australia. My paternal grandmother was one of the younger daughters of Henry.I would be interested to know to which line you belong. There have been a few lines I have been trying to follow up without success. Are you in Western Australia? I would be happy to correspond with you perhaps we may be able to correspond off the forum.
