The history of the last name Lasiloo

The surname LASILOO is of ancient Scandinavian origin, with its roots traceable to the Old Norse language spoken in parts of modern-day Norway, Sweden, and Denmark during the Viking Age (793-1066 AD). The name is believed to have derived from the Old Norse words "las" (meaning meadow or pasture) and "loo" (meaning hill or mound), suggesting that the early bearers of this name resided in a settlement located on a grassy hill or elevated pasture land.

One of the earliest recorded instances of the LASILOO surname can be found in the Landnámabók, an Icelandic manuscript dating back to the late 12th century, which chronicles the settlement of Iceland by Norse Vikings. The name appears as "Lasilo," referring to a Norse settler who established a farmstead in the southern region of Iceland.

In the 13th century, a variant spelling, "Lasilou," is documented in the Diplomatarium Norvegicum, a collection of medieval Norwegian charters and legal documents. This reference pertains to a landowner named Thorvald Lasilou, who held properties in the Trondheim region of Norway.

During the 14th century, the name LASILOO gained prominence in Sweden, with historical records mentioning a prominent nobleman named Björn Lasiloo (c. 1320-1385), who served as a trusted advisor to King Magnus IV of Sweden.

In the 16th century, the name made its way to Scotland, where records show a John Lasiloo (c. 1510-1578) being granted lands in the Scottish Highlands by King James V. This branch of the LASILOO family is believed to have descended from Norse settlers who migrated to Scotland during the Norse-Gaelic period.

Another notable individual bearing the LASILOO surname was Ingrid Lasiloo (1625-1692), a Swedish merchant and ship owner who played a significant role in the Baltic trade during the 17th century. Her success in business enabled her to amass considerable wealth and influence in the port city of Gothenburg.

In more recent times, the LASILOO name has been carried by several distinguished individuals, including the Norwegian explorer and author Nils Lasiloo (1845-1912), who documented his travels in the Arctic regions, and the Swedish painter and artist Signe Lasiloo (1875-1948), renowned for her vibrant landscapes and portraiture.
