#5 Real: The Usos and Roman Reigns
The Usos are obviously related since they're twins, but since the split of The Shield, WWE has been pushing the fact that Roman Reigns is also related to the former Tag Team Champions.

The Usos' father, Rikishi, is the nephew of Roman Reigns' father Sika, who once wrestled as one half of The Wild Samoans. This makes The Usos and Roman Reigns cousins.
In recent years, WWE has allowed The Usos and Roman Reigns to work together on WWE TV with the duo coming to The Big Dog's aid on multiple occasions. The team was known as The Bloodline throughout their time together.
Tamina is also related to the three Supertars but her relation is through marriage since her father WWE Hall of Famer, Jimmy Snuka, married into the Anoa'i family making her a cousin of both Roman and The Usos.
It's worth noting that Roman Reigns and The Rock are not blood-related, as Reverend Amituana'i Anoa'i and Peter Maivia were blood brothers and since this connection, their families have retained that they are related.
