The first Hobbits had been seen in Eriador in the reign of Celepharn's father Mallor. During his own reign, though, their numbers increased as the growing darkness in Mirkwood drove them westward out of Rhovanion. Fallohides and Stoors crossed the Misty Mountains at this time, joining the Harfoots who had been living in the west for a century or more.
Celepharn ruled Arthedain for eighty-one years, and was succeeded by his son Celebrindor.
Notes

The date of Celepharn's birth appears only in The History of Middle-earth volume XII, The Peoples of Middle-earth. It cannot therefore be considered completely reliable.

Celepharn's name apparently (though not certainly) includes a variant of celeb, 'silver'; the second element of his name is somewhat obscure, but may be a form of Sindarinfarn, 'sufficient, enough'. On this interpretation, the name Celepharn would mean 'sufficient silver', presumably a reference to his wealth, or an indication that he was not a greedy King.
