"I wish to declare I have always and in all congregations when I have preached on the subject of the Deity,
it has been the plurality of Gods."
(Joseph Smith, Teachings of the Prophet
Joseph Smith pg 369)
So there are 3 in the Godhead that mean the family of God are Father His Son and the Holy Ghost that would be plural even in the Trinity!
Just refining the plurality of gods thing (we do not have a "God of storms" or the like)
