_e_. Patronymics formed with the prefix _ap_ (for _mab_, son), apocopated (as in the Welsh names _Probert_, _Pritchard_, _Price_, _Bevan_, _Bowen_) to a _p_ or _b_. It is possible that to this class may belong _Prowse_, _Prawle_ (_Ap Rowse_, _Ap Rawle_), _Bown_ (_Ap Owen_?), _Budge_ (_Ap Hodge_?), _Pezzack_ (_Ap Isaac_).
The Christian names from which patronymics are formed are not as a rule very peculiar. There are the usual names of the well-known saints, _Peter_, _Paul_, _Mitchell_ (_Michael_), _John_, _James_ (or in its Cornish form, _Jago_), _Thomas_, _Matthew_, _Francis_, _Dunstan_, _Bennet_, _Andrew_, _Martin_, and the rest, the common general Christian names, _Harry_, _William_, _Robert_, _Roger_, etc., and some less common ones, such as _Julyan_, _Vivian_, _Nicholas_ (_Nicol_, _Nicholl_, etc.), _Colin_, _Jeffry_, _Jasper_, _Gilbert_, etc., and names of Cornish saints, _Keverne_, _Key_, _Gluyas_, _Ustick_ (probably adjectival form from _Just_). Besides these there are a few from old British, or of Breton or Norman introduction, _Harvey_ (_Hervé_), _Dennis_, _Rawle_, _and Rawlin_ (_Raoul_, _Raoulin_, _Rivallen_), _Tangye_ (_Tanguy_, a quite common name in Brittany, from St. Tanguy, one of the entourage of St. Pol of Leon), _Arthur_, _David_ or _Davy_ (as representing the Welsh saint, not the King of Israel), _Sampson_ (representing the Bishop of Dol, not the Israelite hero), _Jewell_ (Breton _Judicael_ or _Juhel_). Some names take a variety of forms. Thus _Clement_ is found as _Clemens_, _Clemments_, _Clements_, _Clemo_ or _Clemmow_, _Climo_, _Climance_, etc., _Ralph_ (_Radulphus_, _Rudolph_, _Randolph_, _Rollo_) is found as _Ralph_, _Rapson_, _Rawe_, _Rawle_, _Rawlin_, _Rawling_, _Rawlings_, _Rabling_, _Randall_, _Rowe_, _Rowling_, _Rowse_, etc. There are also certain names which have a resemblance to Spanish names, _Pascoe_, _Varcoe_, _Jago_, _Crago_, _Manuel_, etc., but no theory of Spanish influence is necessarily to be built upon them, as they are otherwise explainable. As the Cornish had got beyond the matriarchal stage of culture before historic times, we do not find family names derived from names of women, but no chapter on Cornish nomenclature can omit that very remarkable and peculiarly Cornish name _Jennifer_, which is beyond any doubt a local form of the name of Guenivere, the wife of Arthur. A more Frenchified form is still found in Brittany, and the Cornish form goes back to time immemorial. At one time the name of an equally celebrated Queen of Cornwall was used as a Cornish Christian name, for _Ysolt_ de Cardinham possessed the advowson of the church of Colan in the thirteenth century, but except as a modern revival, of which the present writer knows only one case connected with Cornwall, this name is no longer found. Another not infrequent Christian name is _Hannibal_, from which possibly may come the surnames _Hambly_, _Hamley_, and _Hamblyn_. The name is too old in Cornwall to have originated in any theory about the Phœnicians and the tin trade of the Cassiterides, for it is found in times when no one troubled himself about either, but its origin is decidedly a puzzle.
