I don't know if this is a match but I have a Mattie Johnson-McCormick born in August 1861 in St. John's, Clinton, Michigan. She died on December 23, 1927 in Gulliver, Clinton, Michigan. According to my database, she married Casimir Frenette in 1885 in Clare County, Michigan. He was born in 1855 in Lac-édouard, cté Portneuf and he died on March 4, 1904 in Copemish, Cleon Twp, Manistee, Michigan. According to my database they had one son, Ferdinand Frenette, born on January 6, 1890 in Lac-édouard, cté Portneuf, died December 12, 1965 in Manistique, Schoolcraft, Michigan. Could it be possible that Charles is a middle for Casimir or the other way around?. If so, could you send a descendant report on what you know about Charles and Mattie to my personal e-mail at email@example.com?
