This is a reference to Zarya's weight lifting record. This can be seen by her tattoo on her shoulder, and two of her sprays have 512 kgs set of weights.

Widowmaker technically wasn't a member of Overwatch, but she used to be Amelie Lacroix, the wife of an Overwatch agent. Pharah's mother is Ana Amari, a member of the original Overwatch strike team although Overwatch was disbanded before Pharah herself could join.
