I Am Looking to Find the Ancestors of Thomas Trumble Who was Born Approx 1810 IN Ireland He Came to Nz IN 1850 with His Family and I Familiar with...

Thomas Trumble was married to Jane (nee Robinson) and they had a number of children, some of whom were born in the UK. I am not able to find his place of birth/birth record and it seems that he didn't exist prior to departing for New Zealand. Any help on his parents and siblings/ancestors would be appreciated. He died in NZ in 1889.
