Barb, I have (or had) Ahrns relatives from Germany, some ended in Detroit. And I have seen different spellings in the name too. My gr gr grandparents came over in 1833, settled in Minster-Ft. Loramie area. My gr grandparents had 11 children, 3 died young. Their son John Henry (went by Henry) b 1888, married Cecelia Young & moved to Detroit & raised a family. I only have 3 children, Grace, Paul & John. The siblings to John Henry are-Bernard, Marie Mayme, Frank, Anna Elizabeth(Ellen), Charles, Louis, & Richard John.Any connection?
