Note several examples in which the name has lenited following ferch as grammar would expect (Ryffythe, Vathew, Varragh), although there are many more examples where the expected lenition does not occur.

Only one of the occupational bynames is in Welsh, and that one appears in a patronym (and lenites, as expected).
