and at DC:
Superman (Clark and Jon), Wonder Girl (Cassie and Yara), Robin (Tim and Damian), Green Lantern (eight characters at least), Flash (four characters), Green Arrow (Oliver and Connor), Huntress (Helena Wayne and Helena Bertinelli), Batman (Bruce and Jace), Batgirl (Barbara, Cass, and Steph), Wildcat (Ted and Yolanda), Doctor Mid-Nite (Pieter and Beth)...
Note that from that entire list only Huntress can't be disambiguated by real first name, given that they're both Helena. Also, one of the Flashes has the exact same real name as his cousin, Kid Flash, though both are known by nicknames.
