Thomas Biblical Derived from the Aramaic te'oma (a twon). Thomas was one of the Twelve Apostles, some believe a brother of James and Matthew. He doubted the reserrection of Christ, an act giving rise to the title doubting Thomas, used to indicate a skeptic or a chromic doubter.
Thomas German From the Ecclesiastic Greek Thomas, which is derived from the Aramaic teoma ( a twin). The name, borne in the Bible by an apostle who doubted the resurrection of Christ was also borne by many famous saints and martyrs.
Sebastian Latin (an ancient city). Saint Sebastian, an early Christian martyr, was killed in hail of arrows, and was a fravotie subject for Old Master painters. (He is now parton of soldiers.) The name has never been common, though the British have used it somewhat since the 1940s, possibly infulenced by a character in Evelyn Waught's popular Brideshead Revisited. To Americans, it may seem a little too rarefied, and it provides no handy nickname. Trakc star Sebastian Coe
