In 1887, John Bartholomew's Gazetteer of the British Isles described Auchindoir like this:
Auchindoir and Kearn, a united par., W. Aberdeenshire, 8 miles SW. of Gartly sta., containing Lumsden P.O. vil., 15,310 ac., pop. 1514.
The location is where the name "Auchindoir" appears on the modern 1:50,000 map, near to St. Mary's church.
A Vision of Britain through Time includes a large library of local statistics for administrative units.
