James Winfield Jordan dob c1835 galway dod 1907 wellington NZ

He is my gt grandfather, data i know on him is as above from his death cert and that his father was James and mother Maria nee Kelly. He arrived in Australia prior to his marriage to Ellen Theresa Britten in victoria 19 nov 1858, all his children were born in australia excepting his last which was in NZ in 1881 who was my grandfather walter heathcote jordan.

Maria his mother died in Beechworth Hospital Victoria Australia in 1887. Her parents were John Kelly and Mary Miekle so also looking for data on them as well. I have Just found her death cert and extra info on it is that she resided in Australia 30 years so that would point to her arriving in 1857 prior to the wedding so did she travel with James, also of interest is a witness on the death cert signed as richard jordan, could this also be a son?

I cannot find any data on his arrival In Australia or that of his mothers arrival and any other family if there was any, also cannot find any data on his voyage to NZ presumed to be between 1879 and 1881, he is recorded on the christchurch NZ electoral rolls in 1885-6
