I don't think he would think of them often. Occasionally, but not that often. I speculate that Link's parents have died before each game (obvious in OoT, probable in every other game). The only Link that I think would reminisce about any of his relatives at all would be ALttP Link, since his uncle (who he was living with) dies in the first couple minutes of the game.
