LLGR, for the Jubilee anniversary of the Relief Society, teaches we pre-existed with both a Heavenly Father and Mother.
Louisa L. Greene Richards "A Thread of Thought" (written for the Relief Society Jubilee, March 17, 1892) in Richards, Branches that Run Over the Wall: A Book of Mormon Poem and Other Writings (Salt lake City: The Magazine Printing Company, 1904), p. 192
We were there, with God, our Father,
And voted "Thy will be done!"
And our Mother, Queen in Heaven,
Smiled on us, every one.
Smiled on each Eve, each Sarah,
Rachel, Rebecca and Ruth,
Elizabeth, Mary and Martha,
Each daughter that stood for truth.
