|burial stone of Donnchadh Mór Mac Eáin Mhic Lachlainn|
The inscription on the stone is in Latin, and reads Hic iacet Duncanus Mor M'Cane. Captain White commented, 'This appears to be one of those rare instances where we are enabled to identify a mediaeval tombstone in the West Highland with a substantive individual of who there is documentary record.' Indeed so, Donnchadh Mór appears in the Scottish crown records and in the Caimbeul family records several times. Also on the stone, across the top is the 'clan' name Lachlan.
Donnchadh Mór was the son of Ailean Mac Eáin Riabhach Mhic Lachlainn of the House of Dunadd. Ailean was granted extensive lands in what is now Kilmichael Glassary Parish in 1434. He had four sons and each establish their own House within the parish. The four Houses and their locations were 1) Dónal of Dunadd, the ruling line, 2) Donnchadh Mór of Dunemuck, 3) Eáin Riabhach of Killiemuchanock, and 4) Giolla Críost of Creig an Taribh.
While the clan association of this family was Clann Mhic Lachlainn, the surnames used by these related families followed Gaelic traditional patronymics. In several records the family is referred by the name Mac Eáin Riabhach, after the father of Ailean, who obtained the original grant of land. Some of the surnames associated with this family are Mac Ailpín, Mac Dónaill, Mac Donnchaidh, Mac Eáin, and Mac an Leagha (anglicised forms McAlpin, McDonald, Duncan, McKean, and McLea).
The family was closely associated with the Earls of Argyll and appear in Caimbeul family records. Their main function were Captains, but each House had other duties as well such as Tacsmen (administrator lands, in this case lands of the Earl of Argyll) and physicians. As military captains they served both in Argyll and in the many places the Caimbeul hand reached in the 1500s.
