It is said that Sadauji YOKOSE (the ancestor of Narishige YURA), the youngest child of Masayoshi, called himself the Yura clan (Yokose clan) and wielded his influence as a Nitta family (there is another theory that Sadauji was a child of Yoshimune NITTA who was a descendant of Yoshimasa).
なお、横瀬貞氏（由良成繁の祖）は政義の末子として由良氏（横瀬氏）と称して、新田氏の一族として勢力を持ったという（貞氏は政義の子孫の新田義宗の子との説もある）。
