The history of the last name Lassak

The surname LASSAK is believed to have originated in Poland. It is a Polish locational name derived from the town of Lask, located in the Łódź Voivodeship region of central Poland. The name likely emerged during the medieval period, possibly as early as the 13th or 14th century.

The name LASSAK is thought to be a derivative of the Polish word "las," meaning "forest" or "woods." This suggests that the town of Lask may have been situated near or within a forested area. The suffix "-ak" was a common Polish surname ending used to denote someone from a particular place or region.

One of the earliest recorded instances of the LASSAK surname appears in the Tarnów land records from the year 1470, where a certain "Jacobus Lassak" is mentioned. This indicates that the name was already in use by the late 15th century in the southern part of Poland.

Another notable early reference to the LASSAK name can be found in the Płock Grod records, dated 1532. These records document a "Stanislaus Lassak" who lived in the Płock region of central Poland during the 16th century.
