The Family of Pollock Of Newry And Descendants by Hartigan, Allen Stewart. Folkestone: Birch & Co., Printers. 1901
Page 1 - John Pollock, 2nd son of Robert Pollock of that Ilk, Co. Renfrew, and brother Robert Pollock of that Ilk, 1st Bart, is believed to be identical with John Pollock, described in a deed under the Act of Settlement as a "Lieut. of Foote" doing duty in Ireland. References to the pedigree of Pollock of that Ilk, weill by the similarity of Christian names in two successive generations, corroborate this statement. In the Pollock family collections are found letters by Anne, Lady Pollock, concerning this John.
