Here is what I found:
Elmer Nicholas was the son of Joseph J. Nicholas.
Joseph J. Nicholas, born 1857
Wife is: Elizabeth McDaniels, born 1869 (her parents were George McDaniels and Eliza).
Children: William O., born 1887; Luella, born 1890; Henry O., born 1891; Joseph E., born 1895; Verne A., born 1900; Grace, born 1908; Martin, born 1903; Myrtle, born 1905; Aleen, born 1907, Elmer, born 1912; Viola, born 1909; Marie, born 1915. (I believe Grace, Myrtle, Henry, and Joseph E. all died as children as they only appeared on one census.)
