I had figured that Jericho must have been north of Marion. Jericho is not a current place name on any recent map, but to the best of my knowledge, It is nearly exactly where current Heiberger is - I might add that Heiberger is not really much of a town either although at one point it must have been pretty big as well.
Jericho had a population of about 20 people in 1895 and a post office.
