Sonya Browne is a pre-made young adult townie in The Sims 3 for Nintendo 3DS. She has the Athletic, Unflirty, and Slob traits. She has red hair in a hat, green eyes, and sunglasses. She is employed in the Professional Sports career track. She can be made playable by marrying her or asking her to move in. She has a very simiar last name to Jamie Brown who also appears in the game. But her last name is slightly different, so they most likely aren't related.
Not much is known about her early life because she does not appear in any other Sims games.
