I assume this is yours - was Thomas jnr a Thomas James?
Birth James Thomas ROSSITER 1858/ 6233 father Thomas James Mother Mary Ann Jos'Ine O'Shea Crainbourn
I don't find a death for Mary - but no more children either. There are a number of children for Thomas Rossiter and Ellen Dalgleish. I don't see a death for Thomas either - maybe they moved states - you could try NSW (or I need to look post 1901)
Didn't find Thomas, but I found this Death
Death Helena Ellen Rossiter parents Chas Rossiter and Ellen Teressa OSHEA age 40 Melb E 1902 14920
so it seems I have missed a birth c. 1862
and this death
Ellen Theresa Rossiter father O'shea mother unknown died 1909 / 6961 age 73, place Welshpool
One of the others with the Vic CD will find it easier to find spelling variations - I'll send her a note
