Translation of Mei

Any help appreciated in translation of this signature and possible era on a Wakizashi.Photo attached (I hope)


Sukesada

It is "FURUME YOKOYAMA SUKESADA".
The "Furume" reading is uncertain, but the kanji are FURU ("old") and MEI ("signature"). Not sure what to make of that...
I wonder if it could be an "Ato-mei" (lit. "after signature"), meaning a signature that was added by someone else, long after the blade was made. The person signing would have been saying "This is a blade by Yokoyama Sukesada". Just a theory...
