What year was the Temple Square Mission established? Remember, the Salt Lake Temple was not dedicated until 1893.

“It seems that a party of the mob had come to Golding's Point [located between Nauvoo and Carthage] on their way to Nauvoo, and that messengers were sent to them to order them to disperse. At this, their leader, Colonel [Levi] Williams ordered all who were not willing to go to Carthage and kill the Smiths to lay down their arms, and the rest to step out together, saying now is the time or never. This was soon done, and the murderers disguised themselves by blacking their faces and started on their way to shed blood, and came to the place about 5 o'clock in the evening of the 27th [June, 1844].
A young man named [William M.] Daniels, who had given up his gun, went with them, as he said to see what they would do, and was an eye witness to all that passed. He heard Wills say he had shot Hyrum. This Wills was one of the company of Saints (an Irish man) who came with me from England with his wife and two children. He was an elder in the Church. It is understood that he received a wound in the arm from a bullet by Brother Joseph. It took his wrist and ran up by the bone, of which wound he soon after died.”
