Elizabeth A. Whisenhunt - Yancey NC

I am looking for information of Elizabeth Whisenhunt of Yancey Co NC. She was the 2nd wife of Josiah/Joseph McIntire. They resided in Burnsville Township NC in 1860. She was 26, he was 65. Their children were Martin, Hulda, and John, all born in NC. Josiah died 1872-1875, his widow Elizabeth then moved to Washington Co, TN with her young children.

Would anyone know who her parents were, and what happened to her children? Thank you
