Hi! I also have many family stories about being related to Norman Vincent Peale and just returned from a family reunion of the Marvin Lord Bishop's, which are related to the Peale's. I am sending a little info I just found and am hoping this will help somewhat in your search. I will continue my search and forward whatever I find in the future. This info is taken from a site I found called Tri County Obits. It gives Norman's fathers and brothers names:
"MAC DOUGALL..AREA NATIVE DIES; DR. PEALE’S KIN" Mrs. Mary MacDougall Peale, 71, a native of Millport and stepmother of famed minister-author Dr. Norman Vincent Peale, died Monday in Poughkeepsie..
