Beth,
I have been working on tracing Jacob Miller and Catherine Ikemire. I suspect that Jacob is part of the same Miller clan who have intermarried with other Ikemires. He may be the brother of Henry, Yost, Samuel and Frances Miller, whose families moved from PA to OH and then to Owen Co., Indiana. I have found that he and Catherine lived in Crawford Twp., Coshocton, OH in 1850, then Crawford Co., IL in 1860, but by 1870 had moved to Vermilion Co., IL. They and many of their kids seemed to have stayed in this area. I have figured out marriages for Andrew, Sophia, Emanuel, Catherine Jr., Jacob and Louisa. Have you figured out a death date for Jacob? It may be 1902, but if you know I will be saved a lot of chasing around.
