Name meaning "father of many" (7)
I believe the answer is:
abraham
'name meaning father of many' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for abraham that I've seen before include "OT Hebrew patriarch" , "relative of 18 [REBECCA]" , "Bar a ham from playing the Biblical patriarch" , "Lincoln, perhaps" , "The first Jewish patriarch" .)
