I have found Edward Pechin on the 1880 Marshfield, Warren, Indiana census:
Edward Pechin 43 Blacksmith b:Ohio fa: France, mo:France
Mary Pechin 33 b:Ohio
Edward Pechin 15 b:IL
Eugene Pechin 10 b:IL
Oliver O. Pechin 1 b:IN
Jennie Pechin 20 sister Deputy Post Mistress b:Ohio fa: France, mo: France
I believe this Jennie Pechin and Edward Pechin are the children of Peter F. Peachin and Catherine.
