I have a maybe...
I have Leonard Eigenbroadt, son of Charles and Delmetia Wilson Eigenbroadt who lived in the village of St. Johnsville, Montgomery Co., NY. Delmetia's will names her son Leonard who resides in Chicago, Illinois. And, I have old newspaper articles that mention Charles Eigenbroadt of Rockford, ILL visiting his parents Mr. & Mrs. Charles Eigenbroadt of St. Johnsville. One article mentions that Charles Eigenbroadt and his daughter Helen of Chicago, Il are visiting Mr. Eigenbroadt's parents in St. Johnsville.
I have a little more information about this family.
