I stand corrected as it seems there are indeed at least a few good works done with a short mei. Most I have seen weren't so good; seems the sue koto smiths of this group get lumped in with others as mentioned that made a lot of practical blades. I'll keep my fingers crossed that this one turns out to be one of the good ones...
There are something like 18 generations of Fuyuhiro in Wakasa, where the shodai is said to have been the son of the nidai Soshu Hirotsugu (there's the Soshu connection), another 5 generations or so in Izumo, and at least 9 generations in Aki. Then there are handful of others that worked in Bizen, Mino, etc. Thus, it may be tough to pin down a short mei to a specific smith.
