Mekor Dukat was the son of Skrain Dukat and the first cousin once removed ("nephew") of Akellen Macet. He was born in 2360.
In 2371, Mekor's father was to take him to Lakarian City, but the incident of Thomas Riker and the Maquis capturing the USS Defiant made this impossible. (DS9 episode: "Defiant")
Mekor encountered his uncle Macet in the ruins of Lakarian City in 2376. (DS9 - Mission Gamma novel: Cathedral)
