I am searching for information on David Steidley or Stadley(my ggreatgrandfather). I was told by my grandmother that the name was changed, but she did not know how far back. He was born 8-13-1889, place unknown. He was killed at a gunpowder plant in Keokuk, IA. on 11-22-1922. Married to Mae Lorraine LaDuke on 10-19-1914 place unknown. Mother's name may have been Meriam? Any help would be appreciated.
