I am looking for the parents of Helen Ketzel (1894-1984) who married Charles Nixon (1890-1058) in Ohio about 1914. They had one daughter named Mary Ann (b 1917) who married James Morriosn Smith. Helen and Charles lived in Franklin County, Ohio.
Helen went to Ohio State University and was the first women to graduate in Summa Cum Laude in Chemistry.
Helen and Charles are buried in Greenlawn Cemetery in Columbus, Ohio.
