The surname on this one has me wondering whether there might be a brevigraph (or two?) towards the end of it-- that *almost* looks like a "-rum" followed by a "-us" at the end.
Or is it more straightforward, something like "Pherlute"?
Not that either of those makes sense to me, phonetically.
(The image I'm keying corresponds to Book 1, image 38, and this name is on the left-hand side, 3rd from the bottom.)
