Parents: Claire and Jamie Fraser (adoptive father Frank Randall)

Children: Jemmy and MandyBrianna (Bree) grew up thinking that Frank Randall was her father. He loved her and was a good father to her, but after his death, and with her mother Claire's and Roger Wakefield's help, she discovered that Jamie Fraser was really her father. She didn't take it too well at first, but eventually came around (she's very much like him in more than looks). The problem was, Jamie and Claire conceived her in 1746, and yet she was born in 1948. Long story there...
Bree and Roger get close working on the mystery of what happened to Jamie Fraser and his men after Culloden, but she's still finishing college and lives in Boston while Roger is a professor at Oxford, in England. They do the long distance thing for a while (write letters, he goes to Boston, and she and Roger meet for Christmas in Inverness), but just when you think things are working out for them, things get really hairy.
