I don't have a map handy to see where St. Marys, WV is right off. The William Carroll I'm interested in appears on the 1830 Tyler County census. There are two of them, both on page 167, one on line 8 the other on line 12. One is counted in the 40-50 age group, the other in the 20-30 age group. This would make the births before 1810.
