MARIETTA, Ga. -- Every Memorial Day, hundreds of people pack into Marietta National Cemetery to show their respect for the American heroes who paid the ultimate price.
Unfortunately, out of the 18,000 gravestones, about 3,000 are marked with numbers or simply say "Unknown."
But one man has made it his mission to give names to Marietta's unknown soldiers.
Brad Quinlin, a research historian, spends his spare time identifying the men who don't have names on their tombstones. He says he does it out of a passion for history and understanding of sacrifice.
"These men not only gave their lives as a gift to us, but they've remained in unknown graves," he said. "And shouldn't we at least, having the freedom, be able to have the opportunity to identify as many as possible?"
Quinlin identified two Civil War soldiers this weekend, just in time for Memorial Day.
