The National Library of Scotland maps have a "Pikie" and a "Peikie", (but no mill) - however, googling using
"Peikie" and "Fife" brings up a "Full text of Ecclesiastical records; selection of the minutes" which has this -
The millars of Peikie, Parke, Kenlie, and Kingfbarne mylnes, appointed to be fummoned to compeir befor the Prefbyterie the nixt day, for ther breke of the Lords day, by making ther mylnes to goe vpon it.
(The millers later appear, are contrite, and their censure is referred to the several kirk sessions where they dwell!)
