I am not looking at given names on the 1890 Sydney Sands Directory, just some possible surnames
Bilton, Binkins, Binskin, Birkbeck, Birket, Birkett, Bisiker, Black, Blacker, Blacket, Blackett, Bladen, Bladon, Blain, Blair, Blake, Blakeley ***, Blakers, Blakey, Blanks, Blenkin, Blinkhane, Blinkhore, Block, Bluthdon, Blush, Blyth, Blythe,
Should I try the “R” surnames next ?
There’s a Thomas M Blakeley at 18 Crown Road, Sydney
Cheers, JM
