[Joseph F. Smith and Anthon H. Lund to Don C. Walker and counselors Mar. 29, 1910]
All of the children who are of age have [the] right to express their own individual choice as to whom they desire to be sealed, while those who have not yet attained to their majority should wait before expressing their choice. In fact in such an important matter as this it would be well for all the younger children to wait until their judgment becomes mature before deciding to leave their father.
