Thanks for your time. I had found the record for the probate of Mordacai's estate. It must have been very little for in the 1870 census several children were working for other families in the area as servants. Do you of any records or the name of a brick factory in either Sangamon or Greene County? Some of the Johns or Carahar-Johns worked there. I also found Margaret Johns Carahar's grave after much digging in the net, also Sangamon county.
Thanks again!
