Bless you! Marcellus Alexander Griffith was my grandfather, so I can personally vouch for that info.His only daughter, Mary Elizabeth was my mom."Cell's" parents were J.E. (Joe or Joab, Erastus) Griffith and Eudora Attilude Hook.Again, pretty well had that nailed down, but didn't have access to census to make me feel better.It was getting past Eudora's father, Samuel Wellington Hook that was giving me lots of problems.And of course, there are all the name changes, Harvey/Henry, sometimes using first or second names: James/Harvey/Henry or Margaret/Eloise/Elivira, on census'.Anyway your info seems to tie it all together.I wish Marcellus b. 1841? showed up on the 1850 census.Might have been visiting relatives. I think they only counted who was actually in the house at the time.Thank you so much for your time.
