The Rodens of Alabama were primarily descendants of the Rodens of Chester Co SC. Their ancestor was Eszekiah Raughton who came to Jamestown aboard the Bona Nova in 1619.
Some believe he was the son of Sir William Wroughton of England. I have not researched that myself.
The 'h' was added in the mid 1830s to the name by the Rhodens of GA and FL. There is a Roden Cemetery in DeKalb AL. The enumeration is online.
An excellent resource is the Roden Chronologues by Mildred Founier - available online. The name had numerous spellings.
