I am searching for info on Isaac R. YOAKUM and his wife Rachel Sisk. I believe Isaac was b. 17 Feb 1812 in TN and d. 8 Mar 1882 in Texas Co., MO. Rachel b.1820. According to family she was a Cherokee Indian. They had 11 children:
1. Margarett YOAKUM b. 1836 in TN
2. William R. YOAKUM b. 1838 or April 1840 in TN never married
3. Elizabeth YOAKUM b. 1839 in TN
4. John H. YOAKUM b. 1842 in TN, m. Mary Elizabeth OWEN
5. Jessie Franklin YOAKUM b. 20 May 1844 in Bradley Co., TN, m. Martha (MORROW) BEACHUM
6. James C. YOAKUM b. 1845 in TN, m. Milly DENNISON 29 Nov 1865
7. Sarah YOAKUM b. 1848 in TN
8. Simon YOAKUM b. 1850 in TN, m. Sarah GRIGGSBY
9. Nancy YOAKUM b. 1852 in IL
10. Isaac Rite "IKE" YOAKUM b. 8 May 1854 in AL, m. Martha Ann MCKINNEY 12 May 1878
11. Mary Ann YOAKUM b. 1859 in MO, m. W.A. HIGGINS 15 Jun 1877

I find the family on 1840(Bradley Co, TN)-1850(Bradley Co, TN)-1860(Texas Co, MO)- 1880(Texas Co, MO) Census and burial in Clara, MO. I wish to find Isaac's b.1809 parents and siblings.
