Richard Thomas Jessop's father was Richard Jessop born abt 1842 in Tavistock, Devon, England. His parents were Richard Jessop and Elizabeth. I am basing this on Richard Jessop's children's names. His brother's and sister's born in Tavistock were Thomass, Elizabeth M, Sarah E, Hubert Wesley. (Source 1861 Census) His first three children, born in NZ, were Richard Thomas, Elizabeth and Hubert Wesley. Too much of a coincidence for it not to be the righ Richard I think.
