LEIDGREVE, or TRITHENGREVE, was an officer under the Saxon government, who had authority over a third part of the county; and whose territory was therefore called *trithing,* otherwise a *leid* or *leithin,* in which manner the county of Kent is still divided; and the rapes in Sussex seem to answer to the same. As to the jurisdiction of this officer, those matters that could not be determined in the hundred court, were thence brought to the trithing; where all the principal men of the three or more hundreds being assembled by the lathreve, or trithengreve, did debate and decide it; or if they could not, then the lathreve sent it up to the county court, to be there finally determined.
