Help wanted about kanji

Hi I have recently bought three katana's from a Japanese sword seller. A Munetsugu that is a straight sword signed Bizen No Suke Munetsugu. A Nio Mitsukiyo dated 1550 with NBTHK Hozon papers. And a Yoshimori katana? The seller gave me some info about the sword. I have my doubts about the date, early edo period 1640.And about the name. Can someone tell me what the signature says about this?

Thanks in advance!

Greetings, Ed
