Junkerman-occupation not name

Thank you, to all who responded with my request. I am going to try and get a first-hand look at the original document containing the word "Junkerman" then post it for others to review. Perhaps the old geraman script is difficult to translate.
I am assuming that nobody else has seen this term used before. Junkerman
Also the definition between farm-laborer and serf in mid 19th century needs some clarification for me.
