Looking for info on Benjamin Hall, born about 1804, who I found living in Rostraver Twp in 1850 with wife Emiline and children; Elizabeth J., Mary Anne, John E., Benjamin P. and Joseph W. Joseph W. (Wilson) Hall, b: 21 Dec 1848, is my gggrandfather. In the 1860 census they are living in Snowden Twp., Allegheny Co. Benjamin is in Jefferson Twp., Allegheny in the 1870 census minus Emiline. He is not found in the 1880 census. Having trouble with finding Benjamin. Have searched wills, estate records, death records, cemeteries, etc.
