Lancashire is one of England's most populated counties. Lancashire possessed 75 ancient parishes, far fewer than most England counties. To handle a population explosion, the Church of England divided most of the Lancashire parishes into chapelries. The end result was 400 chapelries within the 75 parishes of Lancashire.
Each chapelry (church) kept its own separate church registers for christenings, for most burials, and for some marriages as well. The chapelry was supported by the parish church and the tithes of the chapelry area were paid to the parish priest. Over time many chapelries did obtain "parish" status.
Lists of chapelries and their associated parishes are sorted alphabetically on the pages listed below.
