The Seton's of Mounie, both the 1st and 2nd families, were lineal cadets of the Seton's of Meldrum.  The second family was a direct cadet of the Seton's of Pitmedden.  The lands of Mounie came into the possession of Alexander Seton, 2nd son of Alexander Seton 4^th of Meldrum, before passing to John Seton, of Lumphard, Broomhill and Mounie, 2^nd son of William Seton 5^th of Meldrum by his first wife Janet Gordon of Lesmoir.  John Seton married Marjory Patton of Pitmedden during the early 16^th century, and which connection later brought that house into the family. It was John who enlarged and built the house at Mounie during the mid-1500’s.  His son William sold Mounie to John Urquhart of Craigfintry and his wife Elizabeth Seton of Meldrum in 1623, before their son Patrick sold it to Robert Farqhuar in 1636, it was later re-acquired by George Seton, son of Lord Pitmedden.
