Emily Georgina Campbell of Possil IV wished to retain her surname when the marriage took place, which resulted in the formation of the Carter-Campbell name.

[23] Following the marriage in 1864, Lord Lyon King of Arms in Scotland formed the Carter-Campbell of Possil armorial bearings.

[25][26] He subsequently lived with his wife and children at the family residence of Fascadale, in the parish of South Knapdale in Strathclyde (now Ardrishaig, Lochgilphead, Argyllshire).

[30] The Castle was built by the architect David Bryce for John Campbell of Possil, in Scottish Baronial style.

[34] John Campbell of Possil sold the castle and the estate in 1865 to Arburthnot Charles Guthrie, a wealthy London businessman.
