Solved: Ken Burns "Thomas Jefferson" documentary..

I watched this about a month ago and was stumped on a certain classical song played during the show (when Maria Cosway was introduced). The credits are hard to follow at the end, and I know I have heard the song before. If anyone can identify it, I would sincerely appreciate it!!!

Thanks!

I found it - it's by Antonio Vivaldi "Concerto for Lute, 2 Violins and Continuo in D, RV.93: 2. Largo"
Thanks anyway!
