I think the story relating to the fire accident would have been Ivy born in 1891 as she is listed as Mrs Holman.
I can't find a marriage between Joseph and Ivy as QldBDM only allow marriage searches up til 1940. The possibility is also that they never married.
Edit: There is also a birth for a Harry to Ivy Snr with Holman as last name
