George Crawfurd and George Robertson, A General Description of the Shire of Renfrew, (J. Neilson, Paisley : 1818) apprently mentions the Caldwell clan in and near Lochwinnoch. I feel we all would be most appreciative if somebody posts excerpts. George Crawfurd (d. 1748) authored A Genealogical History of the Stewarts from 1034 to 1710, to which is prefixed a description of the shire of Renfrew. 2 pts. 1710. The Shire of Renfrew continued by Semple, W. 1782. 2nd edn., continued. 1818. Crawford authored Lives and Characters of the Officers of the Crown and State of Scotland from David I to the Union. Vol. I. 1726. There might be contained therein mention of Caldwells, especially William Cauldwell, Lord High Chancellor of Scotland.
