Woodruff spent his 70th birthday working in the temple in 1877. One-hundred and fifty-four women from St. George performed temple ordinances vicariously for women who "had previously been sealed to [Woodruff] vicariously" and those who were related to him, Thompson, or the Hart families. Two years earlier, in 1875, Woodruff performed baptisms for the dead on behalf of 141 of his relatives in the Endowment House, and for over 900 more in that same year. Woodruff accepted Brigham Young's daughter Eudora as a plural wife in 1877; their union produced a son who died shortly after birth. Eudora divorced Woodruff, probably in 1879. Woodruff, Phebe, and their living children (except for Susan) met and performed more temple work, and at this time Woodruff adopted various relatives to himself in the temple. He also sealed five single women to his recently deceased son Brigham. He was baptized on behalf of the signers of the U.S. Declaration of Independence and other Founding Fathers. He stated in a September 16, 1877, discourse that he had been visited by the departed spirits of these men. Many of the proxy baptisms for the Founding Fathers had been done previously in Nauvoo and in the Endowment House in Salt Lake City but the proxy endowments for these men were first done in the St. George Temple. Woodruff also compiled lists of notable men and women, for whom he performed vicarious temple work with the help of Lucy Bigelow Young.
