In 1824 the Society of Advocates in Aberdeen bought the 14th lot of Belhelvie. The York Building’s Company sold another lot, Potterton, to James Harvey, brother of Peter Harvey of Ardo. It remained in his family until his grandson left it to his wife, who then sold it to Mr. Thomas Clapperton of Fochabers. One of his descendants, James, an advocate in Aberdeen, improved the mansion and farm buildings on the estate. It has since been sold and broken up into separate holdings and for a time Lord and Lady Tweedsmuir (she was the MP for South Aberdeen) lived in the Potterton mansion.

Also, you might use Google to look for Belhelvie’s history and churches. There are some ( at least one) of our Clappertons mentioned.
