Jeremiah “Jerry” Walter MacKenzie is the father of Roger MacKenzie, husband of Marjorie Wakefield MacKenzie.

According to Roger’s belief, he was a Spitfire pilot during World War II with the Green Squadron. His plane went down and he was missing in action or MIA. However, it was believed he was killed.

After being shot down, Jerry took a leave to recover from bullet wounds and was recruited by Intelligence Officer Frank Randall. Jerry and three other pilots are tasked with flying low over concentration camps to take phones with cameras mounted on their wings. Before the mission, Jerry is flying in Northumberland when his plane suffers engine failure and he goes down. He’s thrown from the wreck near Craigh na Dun. When he comes to he leans on one of the stones for support and is transported into the past.

Roger finally discovers who the Nucklavee is when he finds William Buccleigh “Buck” MacKenzie lurking around Lallybroch in the 1980s.

After arriving he saw Roger and Brianna and followed them back to Lallybroch where he’s been getting the children to give him food. Roger and Brianna aren’t that happy with Buck because he is reason Roger was hanged. Buck is confused by what happened to him and Roger and Brianna explain they are all time travelers and that Roger his he many times over grandson. Buck’s attitude seems to change and he is invested in what happens to the MacKenzies.

When Jemmy is kidnapped by Rob Cameron, Buck is all in to help track down Cameron and save Jem. Brianna and Roger believe it is possible Cameron went through the stones with Jem to find the Frenchman’s Gold. Roger decides to go back to find Jem and Buck joins him in his travels into the past.
