Koreans began to use patronymic, but formed from the Korean names of their fathers. Over time, the proportion of Christians increased, they were given, in accordance with the tradition of the Russian Orthodox Church, names from the general list of revered saints. And at the moment 80% koryo saram have a record of those educated from such names. This differs from the pattern typical in the US, where Korean American parents often register their children with a Korean given name as their legal middle name (e.g. Daniel Dae Kim, Harold Hongju Koh).
