It is not for us to follow him on his lifelong crusade.[627] The Angevin spirit of restless activity and sleepless vigilance, of hard-working thoroughness and indomitable perseverance, never, perhaps, shewed to better advantage than in this second half of the eventful life of Fulk of Jerusalem; but we have to trace its workings only as they influenced the history of our own land. Our place is not with the devoted personal followers who went with Fulk across land and sea, but with those who stayed to share the fortunes of his successor in Anjou. Our concern is with the father of the Angevin kings, not of Jerusalem, but of England. [627] Its history is in Will. Tyr., l. xiv. cc. 1–27. NOTE A. THE HOUSES OF ANJOU AND GÂTINAIS. All historians are agreed that Geoffrey the Bearded and Fulk Rechin were sons of Geoffrey Martel’s sister and of a count (or viscount) of Gâtinais, or Châteaulandon, which is the same thing--the Gâtinais being a district on the north-eastern border of the Orléanais whereof Châteaulandon was the capital. But the names of both husband and wife differ in different accounts. Fulk Rechin (Marchegay, _Comtes_, p. 375) calls his mother Hermengard; R. Diceto (_ib._ p. 333; Stubbs, vol. i. p. 185) calls her Adela; in the _Gesta Cons._ no names are given. If we could be sure that Fulk really wrote the fragment which bears his name, his testimony would of course be decisive; as it is, we are left in doubt. The point is one of trifling importance, for whatever the lady’s name may have been, there is no doubt that she was the daughter of Fulk the Black and Hildegard. But who was her husband?
