I have traced my Cochran lineage back to (5great grandfather) William Cochran, son of Alexander, who died March 21, 1831.I do not have his place of death. He married Elizabeth McClain in 1794.She died 9/10/1841. They are the parents to(my direct ancestor) John Cochran,born 12/7/1798 married to Catharine Larsons in 1822, and died in Limestone, Clarion, PA on 9/18/1866.John's siblings were Alexander(b.7/12/1797 d.9/21/1850) James (b. 9/22/1799, d.9/24/1824) Samuel (b. 10/9/1802, d.8/10/1873 in Michigan) William(b.2/5/1805 d. 12/25/1859 in Mt.
