O'Sullivan's 'O'Carolan' gives two Planxty O'Rouke tunes, (#144, 145) but neither is O'Rourke's Feast (#199) [Plea Rarkeh na Rourkough in the Neals' collection of c 1724].

Carolan was born in 1670, caught smallpox which blinded him at 18, and he died in 1738. It's a little hard to know what to call planxtys. In the Lees' edition of about 80 tunes, c 1780, only 3 are called planxties, but O'Neill in Music of Ireland calls almost all of O'Carolan's tunes planxtys.
