I wouldn't suggest making too much of this at present, but it is an interesting tidbit: archaeologists recently discovered that there was indeed at least one person named Goliath living in Gath during the time that the Bible says David slew a Philistine giant of that name from that village.
According to the UPI story on the subject, the archaelogist responsible for the find, Prof. Aren Maeir, thinks it very unlikely that the Goliath referred to on the tiny ceramic shard mentioning the name is the Goliath mentioned in the Bible. However, as noted in the Yahoo! story on the matter, Maeir "said finding the scraps lends historical credence to the biblical story."
Many scholars have argued that the story of David and Goliath is a myth made up hundreds of years after the reign of the Jewish king. The scrap indicates that, at the very least, there was indeed at least one person named Goliath in the region during the time the encounter is supposed to have taken place.
