Elizabeth Ann Whitney recalls a prophecy of Joseph (c. July 1842) concerning the birth of a then-future daughter "who would be a strength and support to me to soothe my declining years" and its fulfillment.

In January, 1844, my youngest daughter was born. She was the first child born heir to the Holy Priesthood and in the New and Everlasting Covenant in this dispensation. I felt she was doubly a child of promise, not only through the priesthood, but through Joseph's promise to me when I gave him my eldest daughter to wife. He prophesied to me that I should have another daughter, who would be a strength and support to me to soothe my declining years; and in this daughter have these words been verified. My health was very poor, but I remained strong in the faith of the Gospel, and full of courage to persevere in the latter-day work. My two youngest children were frail little tender blossoms and required the most constant care.
