A.T. Robertson Commentary John 1:44

"Now Philip was from Bethsaida, of the city of Andrew and Peter." — John 1:44 (ASV)

From Bethsaida (απο Βηθσαιδα). Same expression in 12:21 with the added words "of Galilee," which locates it in Galilee, not in Iturea. There were two Bethsaidas, one called Bethsaida Julias in Iturea or the Eastern Bethsaida, the other the Western Bethsaida in Galilee , perhaps somewhere near Capernaum. This is the town of Andrew and Peter and Philip. Hence Philip would be inclined to follow the example of his townsmen.
