PRETTY
As described in historical dictionaries
Patronymica Britannica (1860)
PRETTY. The earliest mention of this name is in the year 1192, wheu Engevan de Prretis attests the grant of the chapel of Hope-cum-Tideswell, by John, Earl of Moreton, to the cathedral of Lichfield. Its subsequent forms have corresponded with the changes of spelling in the adjective, thus : Praty, Pretie, Prettie, Pretty. In the XV. cent, the first of these was in use, and so Leland, born in that century, writes the adjective ; e. g. " a praty town." The name, however, has nothing to do with prettiness, but is derived from the Lat. 2)ratum, a meadow. The Prettys of Scotland and Ireland are of English origin. The name is also found in Italy and in Spain. In the latter country, the family bear for arms, " a gi'een meadow, floM'ered proper." Inf. Edw. Pretty, Esq., F.S.A.
