I have conflicting information on John Roberts. Early research done by a genealogist in the 70s and 80s by a family member had John from Kingston in Surrey, but the same research also listed him as coming on the Maitland circa 1846. John the exile was tried and sentenced in Lancashire in 1844 and spent two years in Pentonville before being transported. On his marriage certificate from 1851 there is no occupation or where he is from.
