Do you know what Susan Ramer's maiden name was? When John Jonas Clouse died on April 15, 1854 he left several children that many seem to appear in the 1860 Clark County, IL census with other families.I have his youngest son as being Cyrus who is with the Isaac Earl(can't read name well on census) in Clark County.
John Jonas Clouse's brother, Jacob, father of Moses, was in Clark County.
Off hand I don't know who the 4 year old John Clouse belongs to yet. You also mentioned that you have a partial cemetery index for the Marshall cemetery, is it posted anywhere online? I know that there are many Clouses buried there and I have several obits from Marshall but I don't know where they fit in yet.
