Named on son Frederick's marriage certificates, but not necessarily his natural father, who name was omitted from Frederick's birth certificate.

Frederick's marriage certificates describe him as a Fell Monger (someone who sells or works with animal hides and skins) (1880 marriage) and a Leather Dresser (1895 marriage)

If he was the father of Robert he must have been alive around 1865-67, but his wife was a widow by the time of the 1871 census, so he most probably died between 1865 and 1871.
