Dannon

The old family name Dannon is thought to have derived from the place name Dunoon (Dunomhainn in Gaelic), located in Argyll and Bute, Scotland, on the Firth of Clyde. The surname Dannon was first found in Ross-shire (Gaelic: Siorrachd Rois) a former county, now part of the Council Areas of Highland and Western Isles in Northern Scotland, which emerged from the Gaelic lordship of the Earl of Ross.
