Bowley Arnold and his wife are buried in the Shelburne, Ont
cemeetary in the plat next to my Grandmother Hannah Matilda Kilpatrick (d/o Bowley) and my Grandfather Andrew Kipatrick (h/o Hannah) and my Aunt Mytle Kilparick.
I too have heard stories in the family of Bowley being a direct descendent of Benedict Arnold.
I know of Josh Arnold becasue my father often spoke of "Uncle Josh" who cleared land and then sold it for farms in the Duferin County area.
It has been a while since your posting so I hoe this finds you well.
