You say you can't find son John after 1860 census, did you notice he is listed as an idiot in 1860?That can mean anything from severe redtardation to being deaf or blind.But, something was wrong with him and he may not have lived long after that census.
The earliest census index online I have access to at home is 1860.Chitty is not that common, and on the 1860 census index for SC there are at least 3 people (female and male) old enough to be a parent of your James all in Barnwell Co, SC.
I checked the Barnwell Co, SC GenWeb site, and you must do so, too.There are 5 people listed on the surname list working on Chitty, and you can email them direct.There are 23 queries with name of Chitty in them.One is a Bob Chitty who is working on your James from the 1860 Panola Co, TX census.If you take your time and go through everything on that site, you probably will find more.
Many researchers bypass censuses prior to 1850, thinking they are of no help.If you have access to census records prior to 1850, check Chitty families that have a male in the right age bracket to be your James.You will at least eliminate those that are NOT yours.
BTW no need toput your eddress out on the main page.Up where your name is underlined, that is a link to your eddress and message history, too.It takes a few seconds for eddress to appear, then it will be slightly out of focus.Just another way GenForum tries to protect us against them old spammers sending their computer in to grab eddresses.
Who is the widow Mrs. A. Russell who lists Mary and George Chitty as her daughter and son on the 1880 census Harrison Co, TX?Are you sure Martha died in 1871?Or, did she remarry again?W.B. Chitty is living with a Miles family in the same county.
