Separate treatment is demanded by that clause in the charter to Aubrey which deals with the fief of William of Arques:—
"Et do et concedo ei totam terram Willelmi de Albrincis sine placito, pro servicio suo, simul cum hæreditate et jure quod clamat ex parte uxoris suæ sicut unquam Willelmus de Archis ea melius tenuit."
The descent of this barony has formed the subject of an erudite and instructive paper by the late Mr. Stapleton.[1149] The pedigree which he established may be thus expressed:—
This descent renders the above clause in the charter intelligible at once, for it shows that Aubrey was to reunite the whole Arques fief in his own holding jure uxoris.
Mr. Stapleton, who prints the clause from the translation given by Dugdale, justly pronounces it "extremely important, as establishing the fact of his marriage at its date with the heiress of the barony of Arques as well as of the comté of Guisnes." With Aubrey's tenure of this comté I have dealt at p. 188.
