Margery Fowell Ancestry

Hello
I am researching my connection to the Fowell family.
I have: Margery Fowell (1520-1575)daughter of Thomas Fowell (1495-1544)and Mary Halse (1499-)
I have conflicting information about Thomas Fowell's parents.
One search indicates parents were Thomas Fowell (1453-) and Maud Brevile (1450-) and another search indicates parents were Richard Fowell (abt.1440-1507) and Blanch Hayes (abt. 1450-).
Can anyone shed some light of this??
Regards
