The "Locksley streets" are called after Locksley House - a large farm which once stood on Lisburn Road in the Finaghy area before the farmlands were all developed for housing. The house stood roughly where St Polycarp's Church of Ireland is today, while the driveway leading to the house ran roughly along the line of Locksley Drive.
Was the name of the house inspired by Tennyson's poem Locksley Hall (1842)?
