I am also researching the finn family, I have a GGGrandfather named Henry finn. I am not sure of his birthdate or place I only have his spouse Jane Haughton and children Robert John my great grandfather, Pauline, Reginald. Robert was born in toowoomba Queensland. I realise this doesn't help you much but am happy to pass on any info I find in the future or any I have now that you are intersted in. If this sounds like the same person I would be gratefull for any information also. He was a miner.
