I have three:
John E. Karpen, b. June 18, 1891, d. April 28, 1972
John Karpen, b. April 07, 1857, d. May 30, 1929, m. Mary Katherine Gerardy
John Karpen, b. January 06, 1850, d. August 26, 1925, m. Mary Wagner
I don't know where they lived their entire lives. Rittersdorf, Trier, Rheinland, Prussia is where the last one was born.
