Pallava or "Pālave" is (a Prakrit form) "Pallava"Vaidya C.V., History of Medieval Hindu India, pg.281
Pālave Maratha" refers to the Pālave or Pallava Maratha family, whose name is a Prakrit form of the historical Pallava dynasty. The connection is based on shared lineage or gotra with the Pallavas, and some historians link the Pallavas to an ancestor named Ashvatthama.
A theory suggests a connection through Ashvatthama, a figure in the Mahabharata. According to this theory, the Pallavas' ancestor was born from Ashvatthama's union with a Naga princess, and the Pālave Maratha family shares the same Bharadwaja gotra attributed to the Pallavas, say.
