The surname AGUILA is a Catalan name of uncertain origin, probably derived from the personal name AGUILA (eagle) and rendered in medieval documents in the Latin form AQUILONIS. In the 8th century, Spain fell under the control of the Moors, and this influence, which lasted into the 12th century, has also left its mark on Hispanic surnames. A few names are based directly on Arabic personal names. The majority of Spanish occupational and nickname surnames, however, are based on ordinary Spanish derivatives. In Spain identifying patronymics are to be found as early as the mid-9th century, but these changed with each generation, and hereditary surnames seem to have come in slightly later in Spain than in England and France. As well as the names of the traditional major saints of the Christian Church, many of the most common Spanish surnames are derived from personal names of Germanic origin. For the most part these names are characteristically Hispanic. They derive from the language of the Visigoths, who controlled Spain between the mid-5th and early 8th centuries. The name is also spelt AGUILA. A notable member of the name was Marian I AGUILO (1825-97) the Spanish writer and philologist, born in Valencia. He worked as librarian there and at Barcelona. He was a powerful influence in the renaissance of the Catalan language and the poetic tradition of Catalonia. He published 'Romance and popular de la terra catalana' (1893), and a dictionary of Catalan was published posthumously. The name has been Anglicized to EAGLES. A certain Solomon Eagles, who was a Quaker musician in London in the second half of the 17th century, was also known as Eccles, and may well have been of Huguenot origin. The Bristol family of this name are probably descended from a certain William Eagles, burgess in 1630. As Bristol traders, they also acquired estates in Carolina whence the name became established in North America.
