In the 1850 census for Greene Co., Pennsylvania, this William H. appears with his wife and three children. Living next to him is Andrew J. Pettit, age 27, and next to Andrew is Silas Cooper Pettit. One of these men is the likely father of William Pettit who married Isabell Farabee, and possibly the John J. Pettit who married Harriet and had son David.
