Origin
Meaning and origin of Marjamaa
The surname MARJAMAA is of Finnish origin, originating from the region of Western Finland. The name is believed to have emerged during the 16th century, derived from the Finnish words "marja" meaning berry and "maa" meaning land or earth. This suggests that the name was initially associated with individuals residing in areas abundant with berry bushes or those involved in the cultivation of berries.
One of the earliest documented instances of the name MARJAMAA can be found in the parish records of Turku, dating back to the late 16th century. These records mention a farmer named Matti Marjamaa, who lived in the village of Marjaniemi, which translates to "Berry Cape" in English. This village name likely influenced the evolution of the surname.
During the 17th century, the name MARJAMAA appeared in various legal documents and land registries across Western Finland. Notably, in 1638, a man named Jaakko Marjamaa was recorded as a landowner in the village of Marttila, near the city of Turku. This indicates that the name had already gained recognition and established itself as a hereditary surname by this time.
In the 18th century, the MARJAMAA surname gained further prominence with the rise of Antti Marjamaa (1701-1768), a prominent Finnish farmer and landowner from the region of Häme. Antti Marjamaa is credited with expanding and modernizing his family's agricultural operations, introducing new farming techniques and improving crop yields.
Another notable figure was Liisa Marjamaa (1765-1844), a Finnish textile artisan renowned for her intricate weaving patterns and exceptional craftsmanship. Her works were highly sought after by nobility and affluent households across Finland and Sweden during her lifetime.
In the 19th century, the MARJAMAA surname was carried by Juho Marjamaa (1812-1891), a respected Lutheran minister and theologian from Ostrobothnia. Juho Marjamaa played a significant role in the establishment of several churches and educational institutions in the region, leaving a lasting impact on the local community.
Towards the latter part of the 19th century, the name MARJAMAA gained international recognition through the accomplishments of Kaarlo Marjamaa (1870-1936), a Finnish architect and urban planner. Kaarlo Marjamaa was instrumental in the design and development of several iconic buildings and public spaces in Helsinki, shaping the city's architectural landscape.

The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. 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.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Marjamaa surname at the time of the 2020 Census, not any inherent property of the name itself.
