LOS ANGELES — Kim Kardashian and her sisters Khloé and Kourtney will be heading to Armenia, the birthplace of their paternal grandparents, sometime in April, sources tell E! Online.

E! says the specifics of the trip are still being worked out for their family milestone journey, but Kim is set to take daughter North West with her, while Kourtney will be traveling with kids Mason, Penelope and Reign as well. Several cousins are also expected to be along for the continent-crossing ride.

Kim’s husband Kanye West will also make the trip, if he can squeeze it in between upcoming concert dates.

“Visiting Armenia has been on Kim’s bucket list forever,” a family insider tells the entertainment website. “They are all so excited! They want to learn about their heritage.”

The sisters have always culturally identified with their Armenian roots, according to E!, which notes that every year they pay tribute to victims of the Armenian Genocide, which occurred in what is now modern-day Turkey.

In March of 2011, Kim appeared on the cover of the inaugural issue of Cosmopolitan‘s Armenian edition. She was quoted in the magazine as saying, “My Armenian heritage means a lot to me and I’ve been brought up to be incredibly proud of my family’s background and culture. So as an Armenian-American woman it is a huge honor for me to be on the first ever Armenian Cosmopolitan cover.”

The Kardashian sisters’ late father, Robert Kardashian, was born to Armenian-American parents and his great-grandparents were ethnic Armenian immigrants from a part of Turkey that at the time belonged to the Russian Empire.
