Betsy Ross was a talented seamstress and upholsterer who was widely believed to have made the first American flag. In preparation for the country’s 200th anniversary, the Betsy Ross Foundation and her descendants wanted to exhume her grave and rebury her remains in the courtyard of her historic home at 4th and arch, where it was believed she sewed the first flag. But when a team of excavators dug under her grave marker in December of 1975 there was nothing at the bottom.
