It is fascinating (to me) to read the letters written in the 1940s.  Such courtesy!  In this case, I admire the devotion of Alvin David Frantz as he searched his ancestry.  He ultimately determined his lineage from Christian Frantz I, II, III, and yours truly (Lorraine Frantz Edwards) had limited information beyond the book The Matthias Frantz Family of Berks County, Pennsylvania.  Alvin David Frantz is not in Frantz Families -- Kith & Kin and I could not locate him on the Ancestry website. Nor is George Frantz of Ladoga, Indiana.  Doing a Ctrl+F search for Ladoga, in Vol. One, I found an interesting narrative from Matthias Gish of White Oak.... Rereading these letters (lovingly transcribed in the 1990s) provided a clue to the ancestry of Frank Frantz, (1872-1941) Governor of Oklahoma Territory 1906-1907 (likewise a descendant of Christian I, II, III).
