My Grandfather Jackson Useldinger was Gregor's brother.
My father Ron Useldinger was Jackson's youngest son.
They lived in Euclid, Minnasota in the 1930's, then came west
to Portland Oregon in the forty's. I am Ron's Daughter Krista
Useldinger, we moved to California in the 1960's and have been here ever since. Was Gregor's wife from the Kirsh line ?
