Charlie Swan — Charlize Swan

Renée Dwyer née Higgenbotham — Reese Higgenbotham

Isabella "Bella" Swan — Beaufort "Beau" Swan

Note: Charlize and Reese weren't married when Charlize gave birth to Beau, which is why he has her surname.

Reese was the stay at home dad, while Charlize worked as a police officer. When Reese left, he demanded he get to take Beau because Charlize wouldn't be able to raise their child while working in order to financially supporting them (Reese came from money). Charlize agreed, because she had recently been promoted to deputy chief of police and was flat-out busy and she thought Reese could give Beau a better life.

And that, Stephenie Meyer, is how you get Beau being raised by a male Renée.
