BUT, 1878 sighting of both Edward and Benjamin PURSS on electoral roll in Newtown (suburb in inner west Sydney!
Line 2743 Purss, Benjamin, Campbell St, household, (ie qualification to enrol, suggesting to me he lived in that household)
Line 2744 Purss, Edward, Campbell St, residence (ie suggesting to me, this was his residence, and that Benjamin lived there too).
Will now try to find them in Sydney in 1870 roll.
