Hi Julie,
Concerning your ancestor Johannes Klinger--no, he would not qualify as a profile that fits the criteria for the Palatine Migration Project. If Johannes Klinger was born in Bavaria in 1810 and died in Oregon, USA, then he immigrated too late for the Project. The Project manages profiles of immigrants arriving from (mainly) what is today southwestern Germany, between about 1708 and 1776. Most of the earlier ones arrived in New York, and later ones in Philadelphia.
