haha.. its sad though fortunate that some people find out about Armenians from the Kardashians
but to answer your question, most Armenians have names that end in -ian or -yan, and those who don’t either changed it while moving to another country or removed the -ian at the end to assimilate easier. I even know someone with -khan at the end.
One other thing that happens with alot of armenians from Russia, is that they change the -ian to -ovich. Furthermore, during soviet times, a russian passport would consist of First name, Last name, and Dad’s first name + ovich.
