There has been a lot of recent attention paid to Clarks in Mercer Co., so I will weigh in with my own set of them in hopes I might press earlier than 1811 in your county. Historical information about earliest settlers at Clarksville and the Big Bend area would be of use also. My line emigrated to Iowa in the 1850s. I have some sketchy information about various siblings. Outlining and numbering generations before me: 4. James Law Clark, b 11 Jan 1811, Big Bend, Mercer Co., PA, d 9 Dec 1890, Wyoming, IA m 6 Mar 1838, Clarksville, PA Jane Blair, b 29 Sep 1818, Bedford Co., PA, d 18 Jun 1897, Woodbury Co., IA: Children Sarah, Elizabeth, John, William, Milton, Winfield, Josephine, Eugene Hamilton Clark (3), Emaransia, Charles, Cornelia, Kezoine, Mead. 5. John Clark, b 3 Aug 1779 m Jane Law, b 12 Jan 1782, d Nov 1852: Children George, Margaret, James Law Clark (4), Richard, Callie, Eliza 6. George Clark, d 1812 m Margaret: Children John Clark (5), Richard, George George Clark (6) Apparently fought in Revolution because wife Margaret resided on warrant land at Big Bend of Shenango R., Mercer Co., PA as widow of Revolutionary veteran.
