Four errors in paragraph? What are they?

Legend says that the American flag was designed by a seamstress, Betsy Ross, who was visited by General George Washington. They were supposed to have discussed various flag designs. Washington's design was composed of seven red and six white stripes and thirteen six-pointed stars arranged in a circle. Betsy convinced him it would be easier for her to cut out five-pointed stars and General Washington agreed. But Washington's diary makes no mention of meeting a local seamstress. The tale was told by Betsy Ross' grandson who claims to have her it as a boy in his grandmother’s deathbed. Weather history or legend, Betsy Ross is now part of American folklore.
