Meaning the parents are disputed (work from child up).
The Edmund Greenleaf who came to America was not the son of John Greenleaf & Margaret Greenleaf according to Wikitree citing:
Greenleaf" New England Historical and Genealogical Register 69:358/9.
"Edmund Greenleaf, son of John and Margaret, was baptized at St. Mary la Tour in 1574/5 and he has been claimed as the emigrant. But, this man was born too early to be the emigrant, who may well have been a son of the Edmund Greenleaf mentioned in the record of the suit given above for the parents of the latter's wife Elizabeth were certainly married some time before 1576."[3]
