Aldrington or Atherington, a parish in Sussex, on the coast, near the South Coast railway, 3 miles W of Brighton, which is the post town; money order and telegraph office, Hove. Acreage, 761; population of the civil parish, 2238; of the ecclesiastical, 2222. A village here, which antiquaries suppose to have been the Portus Adumi of the Eomans, which some also suppose to have been given by King Alfred to his younger son, and which came to bear the same name as the parish, was destroyed at no very late period by encroachment of the sea. So much of the parish also was carried away that not an inhabitant was found in it at the censuses of 1801-31. The church, after having been in ruins for 800 years, was rebuilt in 1878 by the Ingram family, to whom the estate formerly belonged. Parts of the old church, especially the east wall and tower, are incorporated in the present building. The living is a rectory in the diocese of Chichester; net value, £215. The Hove Cemetery, formed in 1882, is in this parish. There is a canal and floating basin. The population has largely increased since last census, and is still increasing.
