Events of the Novels
Drums of Autumn
At Hogmanay, Kenny plays the bodhran to accompany his brothers on fiddle and flute. Later, he and Murdo implore Jamie to perform the Highland sword dance.
In May 1771, Kenny camps with the militia at Alamance. Later in the year, Kenny tells Roger about Thomas Christie and how Jamie started a Masonic lodge in Ardsmuir Prison to calm the conflict between the Catholic and Protestant inmates.
In summer of 1772, Kenny's wife Rosamund dies from a severe allergic reaction to Claire's penicillin treatment, applied after amputation of Rosamund's thumb as the result of an axe wound. Not so much grief-stricken as shocked, Kenny goes with Jamie for application of medicinal whisky, and asks Roger to sing the caithris at her funeral.
A Breath of Snow and Ashes
