Avie I did not find the Caudle's on the 1890 Oklahoma Territory Census. If Isham was in Oklahoma in 1890 he was probably in the Indian Territory and the Census available for 1890 is only the Oklahoma Territory that was opened for settlement in the Land Run of 1889. I checked the 1900 Census and found them up in the Cherokee Nation in northeastern Oklahoma. I have enclosed all of the info from this census just in case you may not have all the info found on this Census. 1900 Indian Territory, Cherokee Nation, July 6, 1900, Township 22 North, Enumeration District #24, Page 20, Line 80 Caudle, Isam W. Born Nov 1850 in Illinois, father from Tennessee, mother from Tennessee, married to present wife(Nellie) 12 years Children from previous marriage, Ross & Grace. Occupation, Farmer, farm is rented & farm schedule is #122 Nellie, wife, born April 1867, Illinois, father from Pennsylvania, mother from Illinois, married to Isham 12 years. Had one child who had died prior to the census of 1900. Ross, son of Isham, born Sep 1879 in Illinois Grace, daughter of Isham, born Oct 1880 in Illinois If I can be of any further help please let me know, I love to search for information, but find it disappointing when I come up empty handed.
