Hi,
There are several Morimichi;
Morimichi ha worked both in Mino and Owari, smiths of this school are descended from the late Koto Smith Muromichi of the Seki Muroya ha.
Two main families with parallel dévelopment each succeding to their own title:
Sugura no kami fujiwara Morimichi (shodai, nidai, sandai)
Musashi no kami fujiwara Morimichi (shodai nidai sandai)
worked in sue-seki style.
Darcy, it is not a eventuality, it is a fact, i have an oshigata of Suruga no kami Morimichi (nidai) wich reads Mishina Fujiwara Morimichi.
