While it is late (February 1884), Oliver B. Huntington recorded the following prophecy of Joseph Smith as recounted by John S. Fullmer:
Bro.
John S. Fullmer was once grieveing in the presence of Joseph Smith because he
had no son—he then had four daughters.
Joseph
replied "Brother John you ned not worry you shall have lots of boys, a
plenty of them"
When
Bro. Fullmer told me this in Feb. 1884 he said he then had 18 boys.
