5) The Gaekwads
Datta Gaekwad represented India in 11 test matches in the 50s. Although in and out of the team, he captained the Indian team which toured England in 1959.
His son, Anshuman, played 40 test matches as an opening batsman in the 70s and 80s. He had terrific reserves of patience and concentration. This is demonstrated by his 671 minute epic for his Test-best 201 against Pakistan at Jalandhar in 1982-83. He later went on to be the head coach of the Indian Cricket Team!
