Hello Patrick, Found your posting from 1998, hope you get this message.
I am searching for information on John Carroll. John married Mary Scanlon, June 8, 1852, Downeyville Ontario. Mary was the daughter of Michael Scanlon and "Catherine Pott". I found a will in the Provincial Archives, Toronto Ontario, for Catherine Herr, dated Nov 1,1867. I believe that this Catherine, remarried James Herr and had 3 daughters, Bridget, Catherine and Johanna. Mary, I believe was from Catherines first marriage to Michael Scanlon.
In the will Catherine leaves sheep and money to her grandchildren John Carroll Jr. and Mary Carroll, they were children of John and Mary Carroll.
The Carrolls and the Widow Herr were neighbours in Emily Township, northwest of Peterborough, Ontario. ( Emily Ratepayers 1867, map in Lilies and Shamrocks, A History of the Township of Emily in the County of Victoria ).
Any information on this family would be appreciated.
