I have only today found your posting. My interest with the Kenning line is through the marriage of Jane Ann Wanless (1842-1882) to Robert Campbell. Their daughter Elizabeth Campbell married John Kenning. All the Campbell family, apart from Elizabeth, emigrated to Australia in 1887, after Robert remarried.
Jane Ann Wanless was the daughter of Thomas Wanless (1815-1886) and Mary Gregory (1811-1882) of Northumberland, England.
I would like to know more about the Kenning family who emigrated to Lincoln, Illinois. Especially when/where Elizabeth Kenning died.
