I am looking for the naturalization record of my gg grandfather, (Johann) Heinrich Schulze  and his brother, Wilhelm Heinrich Dietrich Schulte or Schulze. My gg grandfather came to America about 1837 and lived in Cincinnati until just before 1850.He also lived in Indiana for 7 years and Missouri from 1860 until he died in 1909. How likely is it that he was naturalized while he lived in Cincinnati, Ohio?Where do I find the records? Thank you.JJ
