Illey is a hamlet south of Halesowen in the Dudley district, in the county of the West Midlands, England.
Illey was historically a township in the ancient parish of Halesowen. It was one of the parts of Halesowen transferred from Worcestershire to Shropshire in the Middle Ages, remaining a detached part of Shropshire until it was returned to Worcestershire in 1844. Illey became a separate civil parish in 1866. [1] From 1894 to 1925 it was part of Halesowen Rural District. In 1925 it was incorporated into the municipal borough of Halesowen. It remained a civil parish until 1974, but as an urban parish it had no parish council of its own after 1925, being directly administered by Halesowen Town Council. [2] In 1951 the parish had a population of 133. [3] The parish was abolished in 1974 along with the borough of Halesowen, becoming part of the wider metropolitan borough of Dudley. [4]
