You are probably already aware of this, but many of the Stand Watie letters to and from his wife are now online from the Univ. of Oklahoma. They are a great read. They had 5 children, all who died before leaving children of their own.

A snip from a letter from Sarah Caroline Bell Watie (Sally) to her Husband Stand Watie. Lamar Co. Tx.
May 21, 1865.
"I hear that Cooper will not give you any supplies. if he does not I believe that they all are speculating of it and I hope that the last of them will sink. I do not want you to do any thing of that kind I would live on bread and water rather than have it said you had speculated of your people I believe you have always done what you thought best for your people and I want it to die out that bad belief. if I thought you was working for nothing but to fill your pocket it would trouble me a great deal but I know it is not else it would have been filled before this time. I know that you are capable of making a living any where if we are let alone after the war is over."
