Hi,
George & Margaret Bint's daughter, Letitia who married Ernest Charles Newton Hayward apparently died in 1962, Ernest in 1944 both in Victoria. According to a public family tree on A***y they had 4 children George 1891, Charles 1892, Minnie, 1895 and Ula 1897. However there is no further info on George & Margaret Bint.
A Letitia Bint birth was registered in 1872 Melbourne, Victoria to parents George Bint and mother Margaret nee Ryan. If this is your George, it means he either arrived 1872 or earlier which seems to be the case as his name is mentioned in The Argus 21 Aug 1872, page 5, as being 'Geo. Bint, foreman of machinery, paid 235 pounds' as the salary paid by the Royal Mint, Melbourne
