Searching for information about Tyre/Tyri KELLY, b. ca. 1815-1820, Tennessee and his wife, Delilah.

In 1850, Tyri KELLY is living in Meigs Co., TN, with wife, Delilah and children, Polly Ann, Louisa E., Susannah C., James, Elizabeth, and Martha.

In 1860, Tyre KELLY is still living in Meigs Co., TN (8th Civil District - Moores Cross Roads Post Office), with wife Delila and children, Mary A., Louisa, Susan, James, Lena, Martha, And? (possibly Andrew), John, and Catherine.

By 1870, Tyre/Tyri KELLY, is likely deceased as his wife, Delilah is now head-of-household and living in Rhea Co., TN (4th District-Sulphur Springs Post Office), with children, Louisa, Martha, John, and Catherine.

I can't find Delilah (Nee?) KELLY or her family after 1870.

Any help would be appreciated.
