Petali on Family Tree Circles

I am trying to find a connection with Richard DONOVAN & 5 other DONOVAN'S (all related to each other)he shares a grave with at Cornelian Bay Cemetery.
Richard was born 1851 Albany Western Australia...father Richard (policeman) & Mary ROACHE (both were from Ireland but married in Sydney)...children were Margaret...Caroline...Richard...Thomas & William...think there was one deceased...Margaret was married in Ireland to a John WESTWOOD before this...they had 4 children. Richard married Susan CAPON 1875 not sure how many children but they did have one called Richard another Edith...there is also a funeral notice for another. Richard was a law clerk but owned more than one pub & dabbled in horse racing producing Dunlop the winner of the 1887 Melbourne cup...he eventually went broke according to an inquiry he had too many horsess & gambled more than he made. Not sure when Richard & Susan parted their ways but it was before 1903 because he is in the Tasmanian census that year. Susan continued in the hotel business...the census has her as hotel propieter & Edith living at a hotel in Melbourne. Richard died in Hobart 1927...he was the 4th person to go in the grave.
The other occupants are all descendants of convicts Thomas DONOVAN & Bridget LYNCH also from Ireland.
