I was wrong about John and Jane Baird. It appears that my relation was James and Jane Baird; born 1796 and 1800 respectively. I find them in the 1850 census for Clark Twp, Brown Co., Ohio. Their children are Alexander 26, William H. 25, Nancy 23, Martha J. 21, Eliza 15, and my 2ggrandfather James C. 11.
