I think that the 1851 census gives us the link to Chirk. It fits with the later censuses for birthplace of Mary Ann:
1851

Mary Hall, wid, 70, hand loom weaver, parish of Durrown (??)
William, lodger, mar, 50, do, b. do
Jane, lodger, mar, 38, do, do
Mary Ann, daughter, 3, b. Wigan
John Jones, lodger, mar, 25, collier, b. Denbyshire, Chirk
Mary Ann Jones, lodger, mar, 22, reeler, b. Lancashire, Hindley
