John Aloyius O'BRIEN {M} = Eileen Therese QUINN {F}

Died Friday 14 March 1975, Mt Eliza

Eileen Therese QUINN:

Born Tuesday 10 November 1891, Marshaltown
Died Wednesday 7 December 1938, Mornington
Eileen's death reg as Bretherton. No marriage record found as Quinn, O'Brien or Bretherton in Victorian records.

I'm assuming if this marriage occurred it was before O'Brien because child by name of Bretherton was born in 1905, and O'Brien child was born 1915.
