Hi there
1903 Electoral Roll for East Sydney, polling place Fitzroy (ie Darlinghurst the suburb is in the ward Fitzroy)
M'Sweeney, Maggie F 40 Darlinghurst Rd, nurse. I looked at other polling places for East Sydney, did not see Morgan McSweeney, sorry. 1903 was first opportunity for NSW females to be entitled to enrol, it was not compulsory to enrol at that time.
Cheers, JM
