Re: Searching for Marion Eli Throckmorton ancesters.
Your Throckmortons are probably connected to my Rutherfords who were also in Davis County, Iowa in the late 1840's-early 1850's. John Throckmorton married Mary Jane Rutherford 29 Aug 1843 in Ross County, Ohio. According to all census records, Lewis Ambrose was born in Ohio before they moved to Iowa about 1846. Lewis' sister, Elcy Lavina, married another Rutherford from Davis County who I also believe is connected to mine.
So I'm wondering if you have any more information at all about your Rutherford line?
