KILBURN, a hamlet in the parish of ST-JOHN-HAMPSTEAD, Holborn division of the hundred of OSSULSTONE, county of MIDDLESEX, 3 miles (w.N.W.) from London. The population is returned with the parish. The village, which is situated on the ancient Watling-street, on the road to Edgware, contains some good houses occupied by genteel families, the short distance from the metropolis rendering it a desirable place of residence. There is a medicinal spring, called Kilburn wells, the water of which possesses aperient properties. Near the close of the reign of Henry I., a Benedictine nunnery, dedicated to the Blessed Virgin Mary and St. John the Baptist, was founded here on the site of an ancient hermitage, the revenue of which, at the dissolution, was estimated at £121. 16.
