Hi Brenda, Haggs Colliery was in the parish of Denny in Stirlingshire. Ian Winstanley has copies of the 1842 Report on the Employment of Children and Young Persons in the Collieries and iron works of the East of Scotland, and the State, Condition, and Treatment of such Children and Young Persons. This report mentions Haggs colliery. You can view the index to the report at: http://www.cmhrc.pwp.blueyonder.co.uk/esct.htm Another local colliery was Banknock. Cheers Jim Rouse
