Erum, Eram or Iram [pronounced as (I)slam + (RU)n + (M)ake] according to some Islamic sources is the grandfather of the founder of the Aad nation, the nation of Prophet Hud, whose story of destruction is mentioned in the Quran. The name itself is used in Quran 89:7-8: "Iram, which had great pillars. Like of which were never built in any country." Iram is said to be son of Sam, son of Prophet Noah.
Some sources say it is the name of the garden or city that Shaddad son of Aad (from the Aad tribe mentioned above) built to make it a "paradise" on earth. The story says that once the garden was finished he tried to enter it but he fell and died, as a punishment from Allah for his arrogance and trying to compete with Allah.
Eram is also a girl mentioned in Shahnameh. It is also a Farsi word meaning landmark in the desert, an object in a desert, such as a large rock, that helps people determine where they are.
Eram/Iram is also the name of many places in Iran.
You can use this name if you like it, though some scholars do not like it due to its relationship with an evil and destroyed nation. But you can use it and by it mean the Farsi name not the Quranic name, and this way it will have a neutral meaning.
