A possible descendant of Lachlann's was one "Lacclannus mcmuredhaich archipoeta", who witnessed a charter of Aonghas of Islay, son of the last member of Clann Domhnaill to be recognised as Lord of the Isles.

Other members of the MacMhuirich family, possibly one or two, composed poems of Aonghas's murder that are preserved in the Book of the Dean of Lismore.

[9] Following the collapse of the Lordship of the Isles, the MacMhuirich family appears to have been chiefly employed by the chiefs of the MacDonalds of Clanranald (Clann Raghnaill).

John's successor, the similarly named Rockerick MacLeod "the Younger", was an absentee landlord for whom Morison composed Oran do Mhac Leoid Dhun Bheagain ("A Song for MacLeod of Dunvegan"), rebuking the chief for not performing his traditional duties to his subjects and failing to support traditional Gaelic culture.
