What is "westham"

Westham is a large village civil parish in the Wealden District of East Sussex, England. The village is adjacent to Pevensey five miles (8 km) north-east of Eastbourne. The parish consists of three settlements: Westham; Stone Cross; and Hankham. The parish is virtually part of the Greater Eastbourne conurbation, and much expansion has been occurring here: hence the large population.
