Hi Sylvia This family was living at 123 St Georges Road, Bolton in the Parish of St George. in 1871 John Gerrard classed as Iron Monger (Employer of 2 boys) Couple of additions to your list in 1871- William A Gerrard (aged 17 or 7) and Thomas Gerrard aged 10. Dont know if you have them in 1881 - but they had moved to Rivington and John Gerrard (Head) was the Inn Keeper of the Black o'moor Head Public House in Rivington Villiage. Hope this helps Regards Andrea
