Atwood married to Lydia Metcalf in Indiana 1839

I had Lydia Metcalf (b. 1821 in Indiana) married to Robert Atwood (his name from Metcalf family history)HOWEVER, after researching on the Internet, I discovered that an Eli Atwood married Lydia Metcalf(e) 17 Jan 1839 in Kosciuski, Indiana.I can't find anything that shows this Eli had a middle name of Robert or initial "R".I haven't been able to discover the names of his parents either.Hoping Indiana has records that aren't on the Internet that might help.
