I checked the Isabella Co Genweb after I sent my emaill to you and checked the Clarke Historical Library at CMU. It has a book online through the County Genweb site. This book "Portrait and Biographical Album of Isabella County,MI) Chapman Bros, 1884 had on pages 384 and 386 some info on John Delo. He was born Thanksgiving Day 1817 in Germany to Frederick and Christina Delo. He had 10 children total. Fred, Charlie, John, Minnie, Mary (possibly mine?), William, Caroline, Hettie, Emma, and Asa. There is more detailing his life. Hope this helps!
