My great aunt, Frances J. Shaw, married George O. Rotroff in Indiana sometime before 1910.She was born in 1894 in Missouri and he was born May 1881 in Indiana.His parents were John Rotroff and Rebecca Coin.Frances and George had 4 sons, Herold, b. 1911, James N., b. 1913, George L., b. 1915, and, Rutherford, b. 1922....all born in Indiana.I am looking for more info on any of the family.George L. worked for many years at the Indianapolis Speedway but I'm not sure in what capacity.His wife's name was Helen.Hopefully, someone out there is working on some part of this line.
