Lavasani

The Lavasani family (also transliterated as Lavassani) is one of Persia's oldest and most prominent. Most of its members now live in Tehran, but it originated in the Lavasan region; genealogists have traced its history as far back as the early days of the Qajar dynasty. All of the branches of the family are originally from the city of Lavasan. The name Lavasani means "one who is from the city of Lavasan" in Persian.

Although there are many people named Lavasani today, not all of them belong to the mainstream family. The members of the original family nowadays include affluent physicians, surgeons, Generals, architects, designers, artists, judges, translators and professors with broad education in Iran, Europe and the US. Their long lineage stretches back to the 13th century under the Seljuq dynasty.

Lavasan has two parts: Great Lavasan (Lavasan Bozorg) and Little Lavasan (Lavasan Koochak). Currently Great Lavasan is less populated than the Little Lavasan due to influx of new residents moving to Little Lavasan from other cities. Great Lavasan has access from the Jajrood road while the Little Lavasan has access from the Behind the Latian Dam and have different areas including Saboo Bozorg, Saboo Koochak, Tork Mahale, Seied Paiz etc.
