I am starting with your great grandfather, Charles.Do you know his middle name or initial, date of birth, date of death, place of birth, place of death, where he lived, his occupation, information on brothers and sisters, etc?
I would like to narrow my work down a little because I found: twoC. Neuffers twoC.H. Neuffers seven Charles Neuffers oneCharles A. Neuffer oneCharles August Nuffer (not mis-spelled) oneCharles Carl Neuffer oneCharles D. Neuffer oneCharles Frederick Neuffer oneCharles Fredrick Neuffer and three Charles P. Neuffers.
They all have different dates of birth, etc.
It would be helpful to have any additional information at all on your grandfather, Jacob Henry, as well.I found information on thirteen different people who could be your grandfather.
