I see that you are the one who has the posting of the 12 Cribb brothers. My line comes from a Jonathan Cribb b. abt 1680 England with "2 sons" to the states.
I have been working on Cribb/Cribbs in Georgia for several years now and have gathered a lot of census information on many lines not ours. There is a Samuel Cribb in Camden Co, in 1870 b. England about 1820. There is also a Thomas Cribb, but don't remember the details on him, not sure if he was born England or SC. I will look that up and get back with info on that. Have you gathered anymore information. Do you know when they came from England? I hadn't seen Samuel before 1870 that I can recall. He is in that census with his wife and a Daughter, Ellen R. Ellen is older and living at home.
This is off the top of my head. Don't know if you have gleaned anymore information than this. I would like to see what you have on the 12 brothers. I realize it isn't my line and I don't need to see complete descendancy lines. Just curious!
