Jamie has a son named William Ransom with Geneva Dunsany, who died during William's birth. Jamie also has two stepdaughters, Marsali MacKimmie Fraser and Joan MacKimmie, from his marriage to his second wife, Laoghaire MacKenzie.
After the dust has settled, and with assistance from Ned Gowan, Jamie's marriage to Laoghaire is declared invalid – as Claire was clearly still alive – and he agrees to pay her a yearly fee and provide a dowry for each of her two daughters.

While Brianna knows who William is, William does not yet know that Jamie is his father and that Brianna is his sister. He doesn't discover the connection until late in book seven, when he finds himself in Jamie's company and finally sees the resemblance between them.
