I can't help you out with the McKinney's, but maybe you can help me out with the Knowland's. Floyd A. Knowland was my gr-grandfather. His brother was George O. Knowland according to an obituary I have. Their father was Grant Knowland. Floyd was a native of Underwood, Clark Co., according to his obit. At this point I'm lost! If you have any info you could share relating to any of these Knowlands, I'd love to hear about it.
