Vivian Family Tree

I have a connection to a branch of the Vivian family in Victoria.
Isaac Hanibal Vivian was born to Mary Jane (nee DELBRIDGE) and George Richard Rowe VIVIAN on 17th February 1863 in Castlemaine Vic.

I know where he ended up (died in Brisbane, after marriage to Minnie Jane Moore and having 2 children, Hazel and Goffrey)
I am also looking for his wife's family of which there are few records.
