Tracy, I went to Google and entered 'slaughterhouses Cincinnati 1800's' And got some hits that might be of interest to you. Give it a try and see if you find anything of help to you.
Thank you. I will. Until today I hadn't thought about googling for Cincinnati's slaughter houses. I have been so focused on " How did Thomas' son John get from Cincinnati to Mobile without his parents" that I really hadn't focused on Thomas much. However, typing things out tends to help me process the gajillion thoughts in my head. Thank you very much!
