I have very little information on the part of the family who went further west from Ohio.
John Johnson Needels and Ann Hatfield Needels went to Atlantic, Iowa. The children who are listed for them were Nancy, William, James A, Johnson H and George W.Maybe in looking at them, you can find the Missouri people.
I do know that somewhere in this book I have, there is mention of some others who did go to Missouri.I am still looking.
Also, recently, there was a book published about the Missouri families.I am sorry that I can't give you the name at present - I did recieve a notice, but my filing is actually years behind. It is in a stack somewhere here in my office.You might try looking for it.
Have you seen the Foster Needles web-site?Maybe he has something in that.
Best I can do for the moment.Still looking and if I find anything which might help you, will post again.
