[Wilford Woodruff marriage]
Mary Ann Jackson (married at the Nauvoo Temple or at Winter Quarters) Mary Ann was twenty-eight, Wilford was thirty-nine. They had one child, James Jackson, but divorced in 1848.
... Wilford Woodruff met her on his English mission. In his journal, on August 8, 1845, he wrote: I recieved 2 letters & wrote 2. 4 m. Sister Mary Jackson commenced labour with us this day."
On August 2, 1846, Woodruff wrote: During the evening President Young And Dr Richards Called at my tent. President Young deliverd an interesting lecture upon the priesthood And the principal of sealing there being present: Phebe W. Woodruff / [Mary] Caroline Barton / Caroline [mistake for Sarah] Brown / Mary Jackson." There is a picture of a large heart with four keys. This is a typical pre-1852 cryptic reference to plural marriages. On August 8, at a time of rebaptisms, Woodruff baptized the trio, and got the names right: Caroline, Sarah, Mary." He also has the names correct on August 26: Caroline Barton and Sarah Brown." He describes them there as members of my family."
... Working for the Woodruffs as housekeeper [in Liverpool], she returned with Phebe and a party of emigrants via New Orleans in January 1846. On April 15, two days after his return to Nauvoo for a reunion with his wife and children, Wilford and his family and friends visited the temple. The records are contradictory, but he married Mary Ann on that occasion or on August 2, at Winter Quarters. ...
