Need info on the Reddenhouse/Rittenhouse Family - in Fayette County

Hi!

I'm trying to track down information on the Reddenhouse/Rittenhouse Family.I have found that an Ellen Reddenhouse married a Thomas Smith on 10/18/1849.I believe this husband and wife moved to Union County within the next year.I believe Ellen may have had a brother by the name of John Rittenhouse - who ended up in Hancock County in 1860 - married to a Malinda Smith (their marriage took place in Shelby County).Trying to determine if John and Ellen were possibly related?I believe the correct spelling of the name is Rittenhouse, and the name in the marriage database at the State Library is spelled wrong.Any help???Thanks!
