Monticello has a nice page with quotes about Thomas Jefferson and Independence Day activities. Here are July 1 entries:
1806 July 1. (Jefferson to Thomas Digges). “He [Jefferson] will be happy to see Mr. Digges and his friends on the fourth of July, and to join in congratulations on the return of the day which divorced us from the follies and crimes of Europe, from a dollar in the pound at least of six hundred millions sterling, and from all the ruin of Mr. Pitt’s administration.”[12]
1808 July 1. (Ellen Wayles Randolph to Jefferson). “There is to be a great Barbecue on the 4th of July in Charlottesville to which Sister Ann is going.”[13]
