Ambrosden, a village and a parish in Oxfordshire. The village stands near the river Ray, 2 1/2 miles SE by S of Bicester, which is the nearest railway station. Its name is supposed to have been derived from Ambrosius Aurelius, the British Merlin, who encamped here during the siege of Alccster by the Saxons. Denton was the name of the lord of the manor at Ambrosden in the 16th century. In the year 1604, the manor having been some time previously purchased by Margaret Whethill, it was left by her to Sir Thomas Mild-may, of Chelmsford, Essex. In 1673 Sir William Glynne, first baronet of that name, purchased the estate, abandoned the old manor house, and built Ambrosden House on the rising ground near the church. The estate after this was bought by the Turners (later the name "became Page-Turner). Sir Edward Turner, Baronet, was " of Ambrosden House, Oxfordshire," when created a baronet in 1733. The second baronet, Sir Edward Turner, erected a larger house on the site of that built by Sir W. Glynne, and laid out Ambrosden Park, which is situated in the NW portion of the parish. Ambrosden House was taken down entirely in 1777 by Sir Gregory Page-Turner. The parish includes also the hamlets of Blackthorn and Arncott.
