Tamara isn’t given a last name when I checked on OUAT wiki: http://onceuponatimeabc.wikia.com/wiki/Tamara
But her character description did match up well with another character:
her casting call describes her as “African American, Late 20s to mid 30s. She’s beautiful, artistic, relaxed, friendly, charming and smart. She’s also ambitious, fearless and a born leader, and she won’t stop until she gets what she wants”.
That sorta sounds like Tinker Bell, who was very ambitious and a little head-strong. Also, she could pair well with Felix, who's a 16-year-old boy being cast for 2×22, and is described as “the tough, natural born leader of a “sinister group of boys.”
