Hi,
I am a decendant of Joseph Eiberger, who was possibly a brother pf Balthas Eiberger, some documents said that 3 brothers came over, our line stayed in Illinois while the others moved on to Missouri, this is where you will find a wealth of info on Balthas Eiberger. There is a large family in Missouri, they have done extensive research and are still looking for some lost lines of theirs. scroll through messages and you will find them. Good Luck.
Lois
