The _Toischeachdor_ derives his name from _Toisech_, and _Dior_, an old word signifying ‘of or belonging to law,’ and is obviously the same as the Manks _Toshiagh Jioarey_, and this office is not to be found in those eastern districts where the thanages prevail, for the simple reason that it is there represented by the _Toschech_ or Thane himself, but the _Toiseachdera_ or Mair of Fee occurs repeatedly in connection with them. Thus in the laws of King William the Lion, which gave the form of citation, it is directed to be made by the serjeand or coroner or _Tosordereh_ or other summoner;[399] and that the serjeand and _Toshachdera_ are the same, will be evident on comparing a charter of the thanage of Belhelvie, which mentions the office of smith and the office of serjeand, with one of the demesne lands of Davochindore in Kildrummy, where the same offices are called _Fabrisdera et Toshachdera_.[400] We find in connection with the thanage of Moravia the office of Mair of Fee,[401] and in 1476 the lord of Strathawin, in Banffshire, grants to Alexander Crom Makalonen the lands of Invercahomore, with the office of _Toshoderatus de Strathawin_.[402] We can trace the appearance of this office too in connection with the church lands in this part of Scotland. One of the earliest grants to the bishop of Aberdeen was the schyra or parish of Rayne. It contained the lands of Ledyntoschach, or the _Toschach’s_ half, and Rothmaise, in which the word _Rath_ appears. These lands were held under the bishop by a family of De Rane, and afterwards by a family called Tulidef, but in 1544 the bishop feus to Mr. Walter Stewart the lands of Invirquhaland, Newmore, and two parts of Rothtmaise _cum ly Derachthowis_.[403] The lands of Tarves, within the thanage of Fermartin, were conferred upon the abbey of Arbroath by Alexander the Second, and in 1384 the abbot of Arbroath confers the office of _Derethy of Terwas_ upon Thomas de Lochane and the heirs of his body in perpetuity.[404] In the thanage of Fettercairn we find, besides the thaneston, or mensal land of the thane, another portion termed _Deray_ lands, or the possession of the _Toschachdera_.[405] These notices will be sufficient to show the existence of this office in connection with the thanages, to which a portion of the land was assigned as official demesne.
