I am new to the list. I live in Northeast Oklahoma. Looking for the family of my gr grandmother. Her name was Mansafee Thunderbird or Thunderburgh b. 1840. Could someone do a lookup in the 1840 Index or Census for DeKalb Co. for a Thunderbird or Thunderburgh family. I found her (Mansafee Poole) "divorced" in the 1880 in Conway County census, with 3 sons. The 3 sons ended up in Muldrow, Sequoyah District I.T. around 1890. Two of them were married there. Mansafee may have remarried and the family moved on to Indian Territory. Hope someone can help. Thanks you so much. Sharolyn
