The identification of Phillis _____ as being Phillis Wakelyn, one of the 4 daughters of Alban Wakelyn named in his will in 1602, is a guess based on onomastics. Gabriel Ludlow was named as a kinsman in the will of George Willoughby, son of Albinus Willoughby.
Essentially, the identification is no stronger than the wife of Gabriel Ludlow was named Phillis, Alban Wakelyn had a daughter named Phillis, and someone decided they might be the same?
Phillis needs her LNAB changed to Unknown.
