Thank you Mr Martin for the prompt response, especially confirming his place of birth. Looks like Andrew R, James Andrew and and Richard CHITWOOD were brothers to Edmond. Father: Ezekiel Chitwood.

E.P. married Frances Parker in July of 1858, and they had three children. While Edmond was away, Frances Parker Chitwood took the children to Cairo, Illinois. Here she and the children contracted measles and were ill when the Bushwackers arrived. The irregulars stole their food and burned their house. Although ill, they were forced to walk fourteen miles to the nearest town where the four then died c. 1 Sept. 1864. Upon Edmond's Chitwood's discharge from the army in 1865, he began a search for his wife and children. Several months, he finally went to Cairo, where a nurse confirmed the deaths by recalling a birthmark on the face of Sarah E. Chitwood b. 1861. James R. Chitwood b. 1863. William Chitwood B. 1859. Deeply depressed Edmond left on foot for Alabama to visit relatives there. Along the way he met and married Mary Elizabeth Hicks. They had eleven children. The family moved to Arkansas and through the years lived at several locations - Meyers, Buckville, Story, Washita and Joplin.
