1860 census shows a Levi Codey Born 1834 and wife Sarah born 1837 with 2 sons
Frank born abt 1857 and Frederick born abt 1858, they are living in Summit,Potter, PA.
I was not able to definitely locate Charles but there possibilites.
They are living with other families so something happened to Levi & Sarah between 1860-1870.
1850 Levi Cody is living in Allegany County (which is right next to Steuben County) he is 16 living with another family, with him is a Harriet Cody who is 19. Everything I seen on Charles says he was born in New York, except for his Find a Grave notation that says he was born in PA.
If you go to OLDFULTONNEWSPAPERS and enter any of the family names you will come acroos many artilces in the Corning newpaper. There is an Obit for Mary Fulford Cody and one for her father george.
If I come across anything else I will pass it along to you.I can do a search in 1865 census for Steuben County.
