Forebear; one from whom a person is descended (8)

Ross

I believe the answer is:

ancestor

(Other definitions for ancestor that I've seen before include "An escort (anag.)" , "Antecedent, forebear" , "One of one's forebears" , "Adam was our first one" , "not being of the modern generation" .)

I've seen this clue in the Sydney Morning Herald.
