James and Catherine ( Stuart) Kinloch

My great grandfather Alexander Kinloch Born Portland Victoria Australia 1854 Died 1933. Parents were James Kinloch and Catherine (Stuart) Kinloch maybe new arrivals in Portland at that time. From were? I believe James drowned in 1856 in Forest Creek in, Victoria Australia. His birth cert. states his parents, his death cert. shows nothing, not even his wife or children. I would like to follow this branch of my family as I am very interested in finding out more about Hereditary Nephritis / Alport Syndrome. My father and Uncle both died young from related conditions.
Also I would like to know if I have other living relatives both in Australia or from the place of birth of James or Catherine.

looking forward to anything, anyone can provide
