I was born in Renfrew and my g-grandmother,Angeline Churchil is the grand-daughter. This is fascinating, thanks for the history and I immediately called my mother, Joy McGregor/McCann/Quattrocchi and told her that she has Irish ancestry.
The book"Founding Families of Admaston, Horton & Renfrew Village" has a section on John Churchill, pages 100-101. Ihave a photo of Angeline Churchill.
