Some historians present a theory that states that Gung Ye was, in fact, a direct descendant of Go Anseung, who had been the ruler of Goguryeo-Guk, which had been a failed Goguryeo revival state. Records of Silla reported that Go Anseung was given the surname of the Silla Royal Family, "Kim." Therefore, Gung Ye's commonly known origin as a prince of Silla was right in a way, but Gung Ye being a son of a king of Silla may have not been true.
