Otto Sr. was my grandfathers brother. The only info that I have is that he was born June 4, 1885 in the Town of Washington in LaCrosse, WI and died Oct 1, 1969. He had a farm near either Middle Ridge or Portland.
Only info I have on Otto Jr is his wifes name and where he worked.
The Karl and Matilda in Audrey Petrella's posting were Otto Sr's parents.
