there are some that survived in various families associated with the Stanleys - the 3 vol Stanley Papers published mid 19th century by Cheetham soc were those that survived in a servant's family but the Stanley family papers are sorely missed - likewise the deliberate bonfire of family papers mid 19th century at Milntown probably took away much of Manx history
btw Knowsley was not the home until restoration - look up my site - Lathom was the Stanley base
