Jerusha Mann

Hello. Searching for info. on my 4th Great-Grandmother Jerusha Mann. She was Born circa 1735 in( Massachusetts?) She married John Headley (1730-1776) around 1753 in New Jersey. Census has her living one of her children after her husbands death in Burke County North Carolina where she died in 1776. I would like to know who her parents were. Some sites have parents as Joseph Mann and Mary Joy Lyon while other sites list them as Thomas Mann and Elizabeth LNU. I can't find any solid documentation of either. Any help would be greatly appreciated. Thanks.
