Surfing and saw your message. John is not on my side of the family tree, however a few years ago I sent out about 100 letters all over the world to Prillers. There are several Johns. Ill check and see what I have and maybe I can help a little bit...
There appears to be my branch of the prillers, all of them seeming to begin in the Illinois area. Ive found Prillers primarily in Washington/Oregon (our branch) Illinois, Maryland, and some in Texas with a smattering of others around the world. Hope to
keep in contact occasionally. Let me know too, of any that you have run into. Im 53, my dad just passed away. But I did just locate my great great grandfather Joseph who was in the civil war and the father of my great grandfather also Joseph. His son
was my grandfather Charles, my father Vern and myself Alan, nad my son is 25 Eric and lives in Las Vegas.
