Battle of Lechfeld
The first recorded member of the family was mentioned in a written letter in 1482 when a certain Erzsébet Bíró of Kide warned a Székely named Lázár of "Zarhegh" to beware of disposing of the estate of Kide to which she was entitled under the title of bride price and dower. During the Battle of Lechfeld in 955 the Hungarian troops were decimated by the Bavarians and Germans.
