Re: McCulloch family of Jefferson Co. Mo.
James McCulloch had one son and four daughters, according to the 1840 census. He is on page 102 of Big River township. I feel you have accounted for three of the daughters, but not the other, nor the son.If the son's age was reported incorrectly in the 1840 census, and he was not under 5, but 5-10, he could be the James R. I am searching for.
The other James McCulloch in the Big River, Jefferson County census is on page 104.He was the husband of Lucy Baker.They had two sons and two daughters born before 1840. This number of children agrees with the 1850 census. Also, this James is on the same page as Charlotte McCulloch, who was his mother.James is listed in the probate estate index as son of James and Charlotte.
