Dante's family name; referred to by Cacciaguida,
D.'s great-great-grandfather (in the Heaven of Mars), as tua
[Par. xv. 92]; il sopranome tuo,[Par. xv. 138].
Cacciaguida, who is said to have belonged to the Elisei, one of
ancient families of Florence who boasted their descent from the
Romans, married one of the Aldighieri or Alighieri, probably of
Ferrara, from whom he says D.'s surname was derived, mia donna
venue a me di val di Pado, e quindi it sopranome tuo si feo,[Par. xv. 137-138].
