I was just reading your post. their is a place that would list Jacobs wife if you know the approximate time frame.http://www2.sos.state.il.us/cgi-bin/marriage
however, I did note that Elijah and Honor married in 1821. and Ransom and Mary in 1854. Are you sure Jacob fits between these two? I found this while searching for my Lindleys. I hope you have more luck then I at this time. Mine are elusive. Good Luck,
