[34799] William's information is from the unverified Safford Family file in Ancestry.com in 2013. Ancestry.com offers: "Fellows Name Meaning - English: patronymic from Fellow, from Middle English felagh, felaw late Old English feolaga partner, shareholder (Old Norse félagi, from fé fee, money + legja to lay down). In Middle English the term was used in the general sense of a companion or comrade, and the surname thus probably denoted a (fellow) member of a trade guild"
[39988] Ancestry.com offers: "Holbrook Name Meaning - English: habitational name from any of various places, for example in Derbyshire, Dorset, and Suffolk, so called from Old English hol hollow, sunken + broc stream. The name has probably absorbed the Dutch surname van Hoobroek, found in London in the early 17th century, and possibly a similar Low German surname (Holbrock or Halbrock). Several American bearers of the name in the 1880 census give their place of birth as Oldenburg or Hannover, Germany."
