FULLARTON, a surname derived from the barony of Fullarton in the immediate vicinity of the town of Irvine in Ayrshire. Traditionally, it was said that the first of the name in Scotland had either Strathclyde Britain, Anglo-Saxon or Norman origin [Robertson's Ayrshire Families, vol. ii. p 85], and is supposed to have accompanied Walter, son of Alan, ancestor of the high stewards, from Shropshire in England, about the beginning of the twelfth century. As Walter, soon after his arrival, received a royal grant of the countries of Kyle (called from him Kyle Stewart), and Strathgryfe, now Renfrewshire, it is affirmed by Chalmers and others, that many of those who accompanied him obtained from him grants of land in that district, and the progenitor of the Fullartons is believed to have been of the number.
The name Fullarton, anciently written Foulertoun, is conjectured primarily to be derived from office or occupation, such as that of a fowler. This conjecture derives probability from the fact that on Galfredus Foullertoun, who, there is reason to believe, belonged to a branch off the family which settled in Ayrshire, obtained from Robert the First a charter of some lands in Angus, together with the hereditary office of fowler to the king in that county, in which office he and his successors were obliged to serve the royal household with wild fowl when the king arrived at Forfar castle, where his fowler was to be entertained with a servant and two horses. Nisbet states that the original charter is in the Earl of Haddinton's Collections. [Heraldy, vol. i. p. 339.]
The first of the Ayrshire family named in unquestionable written evidence is Alanus de Fowlertoun, who lived before the middle of the thirteenth century, and died about 1280. In 1242 he founded and endowed out of his lands a convent of Carmelite or White friars at Irvine.
