[David O. McKay]
... President [N. Eldon] Tanner mentioned that in the Temple book of instructions in London at least, and perhaps in the other Temples, the statement is made that women may be used as witnesses for Temple marriages. President Buckmiller of the London Temple is asking if women can be used as witnesses for sealings for the dead in the Temple, sealing of children to parents, etc. He said that Elder [Howard W.] Hunter says that it is permitted for the living and the question is raised as to whether the same service may be performed by women for the dead. I said that I could see no reason why the women could not so serve. President Tanner explained that in England it is very difficult to get enough men to the Temple to take care of this work for the deceased.
President Tanner mentioned that sometime ago a ruling was made that where a couple had adopted Negro children, those children could be sealed to the adopting couple; that now a question comes to the following effect: A man married a Negro woman by whom he had a child. This woman died, and he married a white woman. He is now asking if his child or children by the former marriage with the colored woman may be sealed to him and his present wife, who is a white woman, after they have been properly adopted. President Tanner asked if the former ruling regarding sealing adopted children to white parents would include this situation. I said there was no reason why it shouldn't.
