Nathan Smith married Hulday Simmons on 5 January 1845, recorded in Pend Co Marriages 1800, page 46. Their bond was dated 1 January 1845 with bondsmen Nathan Smith and Daniel Smith. [Harter, Pendleton County Marriage Bonds 1791-1953, page 31.]
You did not mention Sarah's ages. The death record of Sarah Simmons, white female, died 1 December 1894, age 82, parents: "Hy. & Eliz. Wilfong," born Pendleton County, info given by Hannah Simmons, friend.
Joseph Bodkin married Margaret Simmons on 20 October 1839, PC Marriages 1800, p. 38. Their bondsmen were Joseph Botkin and Silas Simmons. Must be a different Joseph?
Hope something here helps.
