[2][3] Feaver attended Millfield School in Somerset, which produced a number of male tennis players from the 1950s to the 1970s, including Mark Cox and Paul Hutchins.

For over 20 years (1976 to 1997), Feaver held the record for serving the most aces in a single Wimbledon match, 42, achieved against John Newcombe.

[8] He also achieved the remarkable distinction of beating five-times Wimbledon champion Bjorn Borg twice in a week at the Beckenham grass court exhibition tournament in the mid-1970s.

Feaver married South African Alison Braatvedt and has two children Lucinda and James, who is also a tennis player.

John enjoyed a successful career in sport and business after his tennis days, and now lives between Wimbledon and Somerset.
