As in the two previous cases, so also in this case, there is an ancient Celtic name, Geio, to take into account, and to this may be placed the names _Keogh_ and _Keho_, if these names be, as I suppose, Irish and not English. Also the Kay and the Kie in _McKay_ and _McKie_. Lastly, in this, as in the other two cases, there is also a name on Roman pottery, Gio, which might, as it seems, be either German or Celtic. Can there be any connection, I venture to inquire, between these ancient names, Celtic or Teutonic, and the Roman Gaius and Caius? Several well-known Roman names are, as elsewhere noted, referred by German writers to a Celtic origin. It will be seen then that, in the case of all the three names of which I have been treating, there is an ancient Celtic name in a corresponding form which might in some cases intermix. And there are many more cases of the same kind among our surnames. _Wake_, for instance, may represent an ancient name, either German or Celtic; for the German a sufficient etymon may be found in _wak_, watchful, while for the Celtic there is nothing, observes Gluck, in the range of extant dialects to which we can reasonably refer it. So _Moore_ represents an ancient stem for names common to the Celts, the Germans, and the Romans, though at least as regards the Germans, the origin seems obscure.[3] Now it is quite possible, particularly in the case of such monosyllabic words as these, that there might be an accidental coincidence between a Celtic and a Teutonic name, without their having anything in common in their root. It is possible, again, that the one nation may have borrowed a name from the other, as the Northmen, for instance, sometimes did from the Irish or the Gael, one of their most common names, Niel(sen), being thus derived; while, on the other hand, both the Irish and the Gael received, as Mr. Worsaae has shown, many names from the Northmen. So also the Romans seem to have borrowed names from the Celts, several well-known names, as Plinius, Livius, Virgilius,[4] Catullus, and Drusus, being, in the opinion of German scholars, thus derived.
