I have a Adam CLARK b. 1833 Jackson Center, Mercer Co. Pa. This came from his Civil War pension app. What was the name of Jackson Center in 1833. I know that it was called Jackson Center after 1873 I know it was called Satterfield after 1853. But what was it called before 1853, espeacially in 1833. Any help would be greatly appricated. Thank you, Esther Clark McDermott
