1851 C. U. Shepard in Proc. 4th Meeting Amer. Assoc. Advancem. Sci. 312 Rutherfordite..occurs in crystals and grains at the gold mines of Rutherford county, North Carolina... Its name is bestowed in allusion to its locality.
1880 C. U. Shepard in Amer. Jrnl. Sci. 120 57 I have detected along with the samarskite of this locality a few very small crystals..nearly identical with those found in the sands from the gold washings of Rutherford, N.C., named by me as rutherfordite, and which I now consider as belonging to the species fergusonite.
