Jonothan Davenport is the son of Bobby Davenport and Peggy Davenport and the brother of Natalie Teeger.


Even though Natalie had ill feelings for the rest of her family, she has a good relationship with her brother, Jonothan. Jonothan was engaged to Theresa Scott, who turned out to be a black widow. They were engaged and the family was scrambling to get ready for the wedding. Among her crimes of murdering her ex-husbands, she hit Randy Disher with a car to prevent him from identifying her. However, Randy exposed her and Natalie stopped her from killing Jonothan, mending her relationships with the rest of her family. (Monk: "Mr. Monk Goes to a Wedding")
