Keiller History, Family Crest & Coats of Arms
The first people to use the name Keiller were a family of Strathclyde-Britons who lived in the Scottish/English Borderlands. The name comes from when someone lived in the lands of (Easter and Wester) Keilor in the adjoining parishes of Newtyle and Kettins in Angus. The names are still common in the district. 
Early Origins of the Keiller family
The surname Keiller was first found in Angus (Gaelic: Aonghas), part of the Tayside region of northeastern Scotland. "Stephen de Cellar [was] burgess of Roxburgh, 1262. Duncan de Cellario, burgess of Peril 1292 is doubtless Dunkan del Celer, burgess of Perth, who rendered homage in 1296." 
The MacKellar variant with its various spellings is in "Gaelic Mac Ealair, 'son of Ealair,' the Gaelic form of Latin Hilarius, the name of the bishop of Poitiers, commemorated in the Felire of Oengus at 13 January. "
