If that doesn't work then go to www.rootswebcom/~usgenweb/ and do a search by state for Atchley in MO. That is how I first came upon the page. Have you found anything to prove or disprove this to be the family you want?
I found a John A. Beals Pvt Co M, 3rd Iowa Calvary inlisted 10 Aug, 1861, discharged June 1864, his address in 1890 was Francis, MO and his sight was injured in the war (my notes are such a mess I can't decide if it was Phelps Co, MO or Pulaski Co, MO) I copied it with you in mind. Good Luck, Carol
