The photo on the right is Dr WEBB as published in a book on the Mayors of Clare.
He was born 5 March 1818 in London and emigrated to South Australia in 1848, aged 30. He died 9 June 1870 having fathered 16 children. He practised as a doctor in Clare from virtually his arrival until his death and was the Mayor of Clare from 1869-1870.
Is this the same man?
