ErisParker on Family Tree Circles

Thomas and Sarah ROIL left Alton in England and arrived in Nelson NZ on the 'Bolton'. June E Neale has covered this early history in her two books 'Landfall Nelson' 1978 and 'Pioneer Passengers' 1982.
The ROIL family was Henry, Eliza, Harriet, Mary Ann and William.
Henry ROIL married Sarah COLLETT in Lyttleton in 1854 and I descend from this family.
Gwenyth Palmer wrote a book in 1983 called 'Family History of Edward and Sarah James. Thomas and Sarah Roil and Their Descendants' - Gwenyth descends from the JAMES - SIGLEY line. After her book was written Gwenyth and I corresponded on our family research - lives changed directions - does anyone know where Gwenyth's research is? Please let me know.
