He is addressed as the recipient of the Epistles to Timothy.  He was from Lystra, he mother and grandmother Jewesses; his father was Greek and not Jewish.

Tomothy was barely 35 yrs old when Paul, who was nearly twice his age wrote the first epistle to him.He had been converted as a lad by the apostle at Lystra at about 45 A.D. ; and was the most trusted of all his disciples.
