he manor of
ACCRINGTON was a member of the honor of Clitheroe, and was by Henry de Lacy granted to Hugh son of Leofwine together with Altham before 1177. (
fn. 8) It must have been surrendered to the grantee or his successor, for Robert de Lacy gave it to the monks of Kirkstall by way of compensation for the grange at Cliviger which had been recovered from them by Richard de Elland. (
fn. 9) The gift was confirmed by William son of Hugh de Altham for the love of God and for the salvation of the souls of himself, his wife and kindred. (
fn. 10)

Bedlam is unclear.
It's derived from the name Bethlehem, and Bedlam became a generic name for places where 'lunatics' were cared for. Sometimes this was applied to where just one person was looked after.
Perhaps there was a cottage up there that cared for the mentally ill?
