Robert BURKE, who marries Emmeline RILEY, sister of Louisa Florence BELL nee RILEY
........are brothers, and from Ballarat, birthplace of William TITLEY aka BELL?.
and if BURKEs and William TITLEY are from Ballarat does not mean they know one another but might be worth a closer look.
Without seeing the documents relating to earlier family for William BELL, it might be that some details have been assumed by repeated telling ie. children might not be born in Victoria.............. children born but no marriage so registered in mother's name etc
Possibly the divorce matter did not progress beyond preliminary hearing. Divorces were reported in newspaper.
