I'm Looking for Information on the Watterson's. Jacob D. Watterson, the second son of John Watterson, was born in the Greensburg area on July 9, 1811. When Jacob was nine yrs. in 1820, his parents lived in Kittanning Township. Ten yrs. later in 1830, When he was 19 years old, were living in Toby Township. This would be in Armstrong County at that time. By 1840 Jacob D.and his wife Rebecca Hopper were living in Madison Township, Clarion. All three of these places could very well have been the same place due to the establishment of Clarion County in 1839.
