John Griggs lists New York as his place of birth in several US Census reports and his age as born in 1821 or 1822. In the last census of his life, he lists his place of birth as Ohio. His children list his place of birth as Ohio also including John William Griggs Jr. Other family trees list John as born in 1820, in Zanesville, Ohio to Alexander and Margaret Griggs BUT give NO documentation for that information. I am needing documentation to proceed into more distant ancestry. Can anyone help me to know how to find some documentation?
