Origin
Meaning and origin of Hammergren
The surname HAMMERGREN has its origins in Sweden, dating back to the late 16th century. It is a locational name derived from the village of Hammergren in the province of Södermanland. The name is a compound word formed from the Old Swedish words "hammar" meaning "hammer" and "gren" meaning "branch" or "twig."
One of the earliest recorded instances of the name HAMMERGREN can be found in the Swedish church records from 1598, where a man named Johan Hammergren is mentioned as a resident of the village of Hammergren. The name likely originated as a descriptive term for someone who lived near a forge or worked as a blacksmith.
In the 17th century, the HAMMERGREN name appears in the Swedish Census Tax Records, indicating its presence in various parts of the country. One notable individual was Nils Hammergren, born in 1642, who was a prominent farmer and landowner in the region of Östergötland.
Moving into the 18th century, the name HAMMERGREN is found in the military records of the Swedish Army. Carl Hammergren, born in 1712, served as a lieutenant during the Great Northern War and was awarded the Order of the Sword for his bravery in battle.
The 19th century saw the HAMMERGREN name spread to other parts of Europe and beyond. Johan Hammergren, born in 1825, was a Swedish-American immigrant who settled in Minnesota and became a successful businessman, establishing the Hammergren Lumber Company.
Another notable figure was Anna Hammergren, born in 1879, who was a Swedish artist and painter known for her vibrant landscapes and portraits. Her works were exhibited in galleries across Europe and are now part of prestigious collections.
As the 20th century dawned, the HAMMERGREN name continued to make its mark. Sven Hammergren, born in 1902, was a renowned Swedish architect who designed several iconic buildings in Stockholm, including the Stockholm Public Library and the Royal Swedish Academy of Sciences.
These examples illustrate the rich history and diverse accomplishments associated with the surname HAMMERGREN, which has its roots in a small Swedish village but has since spread across the globe, leaving an indelible mark on various fields and cultures.

When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
