1. Simon Best (brother of Rory): represented and captained Ulster, Ireland ‘A’ and Ireland in a career that also saw him capped by Ireland at Schools, Under-19, Under-21 and Under-23 levels.
However, he only won 23 Test caps, which is dwarfed by his younger brother Rory, who played for the Lions, won 124 Ireland caps, and also led the men in green to a famous win against New Zealand in Chicago.
2. Tom Cowan-Dickie (brother of Luke): A product of the Penzance & Newlyn RFC’s youth section, Tom initially developed his rugby through the club and at Mounts Bay School, as did his younger brother Luke.
The 29-year-old, who also plays hooker, first joined the Cornish Pirates in 2010, and signed a new two-year deal in May 2020.
3. Jeremy Itoje (brother of Maro): Despite being a talented forward playing for semi-professional outfit Loughborough Students.
