Did your Benjamin and Sarah also have a son named Lewis b 1816 in Bond later Clinton Co. IL? I'm descended from Lewis, but cannot learn anything about his parents. He was married to Nancy Burnside in 1837. My grandmother recalled her Allen family was from Tennessee.

There was a Benjamin Allen in Bond Co. who married Jane Burnside in 1822. Jane would have been Lewis stepmother and was likely a sister, cousin or aunt of Nancy.

Any help appreciated.
