What information are you looking for? He has an uncle in A Link to the Past, and a grandmother (and sister) and a grandfather in The Wind Waker and The Minish Cap, respectively. His mother was also mentioned in Ocarina of Time and his father in Breath of the Wild - both of them died prior to the events of their respective games.
A throwaway line in The Wind Waker also implies that Windfall Island's photographer, Lenzo, may possibly be Link's grandfather, but there's not enough evidence to say for sure. 18:55, May 16, 2017 (UTC)
