Nancy and Annie were identical twins. According to a cousin, they had the telepathic relationship that you often hear about twins having. They would leave their homes at the same time and meet halfway between, talk and then return home.
After Nancy married Clayton, her second husband, she remained in Toppenish after he moved to Prosser, Washington.
She is buried in the Zillah City Cemetery in Zillah, Yakima County, Washington.
