I recently found that my White Co IL Adams are somehow related to the McClains. Would you have any idea how they would be related? There were also Petit (spelling varies), and Mc Cluney.(could it be McCreary?) This came from some data left to me by my gr-uncle Hobert Adams of Jackson Co IL.(This would be the same general time period you have written about in your query, and early 1900s) Please get in touch if you have any ideas or information. Thanks so much.
