Colonel Stewart took a keen interest in the history of the Appin district and it was as a result of an appeal launched by him that four historical memorials were erected in the district. one marks the spot at Ballachulish where James Stewart of the Glen, an innocent man, was hanged. One commemorates the Battle of Stalc at Portnacroish in 1468. Another marks the grave in Lismore of Donald Stewart of Invernahyle (Domhnull-nan-ord), The forth, at Eaglais Nuadh commemorates the clansmen who were killed and wounded at Culloden, the MacColls heading the list of followers with 18 killed and 15 wounded.
The funeral took place on 16th February at the Episcopal Church of St. Cross, Appin, of which the Rev. Paul MacColl was the first incumbent. In accordance with the old custom signifying the ancient association of the MacCills with the Achnacone family in peace and war he was buried between two MacColls. On one side stood his fifth cousin Mr Ronald Stewart MacColl, Portnacroish and on the other side stood Mr Archibald MacColl Inverfolla. whose family for several generations have been tenants of Achnacone. Many MacColls and members of the Society were also present, the Council being represented by Mr Hugh G MacColl, Ballachulish.
