Chorley is a town situated about 10km north of Wigan, 3km north of Adlington. Jemima Whittle lived here when she married John Harrison (b. 1786) in 1812 at St. Lawrence church in Chorley. We have not yet investigated the earlier history of the Whittle family which may have resided in Chorley for some time.
