His wife died in March 1815, and Crockett asked his brother John and his sister-in-law to move in with him to help care for the children. That same year, he married the widow Elizabeth Patton, who had a daughter, Margaret Ann, and a son, George.

After Polly died in 1815, Crockett married widow Elizabeth Patton. Elizabeth brought two children to the marriage, and Crockett and Elizabeth had three more together: Robert Patton Crockett, Rebecca Elvira Crockett and Matilda Crockett.

Elizabeth Crockett died after an early morning walk from her cabin, at age 72. She was buried in the Acton cemetery. Her remains and that of several family members are in what constitutes the Acton State Park and Monument, the smallest Park in Texas.

Elizabeth's first marriage was to James Patton, her cousin, and they had two children, Margaret Ann, and George.
