Lord in heaven, when I picked this up in my Google alert, I thought you were posting to me. I'm a great-great granddaughter of this Empson Wright. As follows, here is the marriage date and a few other things:
i. Empson WRIGHT. He married Rachel RUBLE 23 MAR 1820 in Clinton Cty, OH, daughter of Samuel (Peter ULRICH) RUBLE and Rachel Reynolds THORNBURG. She was born 1 FEB 1801 in Tennessee, and died 29 MAY 1857 in Randolph Co., IN. Buried in Dunkirk Cemetery.
Yes, I had seen an indication in a history book that Empson was one of the earliest settlers in Clinton County.
