Mierzejewskis in
Countries other than Polska

United States


There are about 9000 Mierzejewskis in Polska today, and about 1000 in other countries, mainly the USA, making a total of about 10,000 world wide. Because Mierzejewskis have been around for at least 25 to 35 generations, the number of people alive with Mierzejewski "blood in their veins" is probably in the millions.

Besides Polska and the USA, Mierzejewskis have lived in Argentina, Australia, Belgium, Brazil, Canada, Czech Republic, Chile, China, Denmark, England, Estonia, France, Georgia, Germany, Ireland, Italy, New Zealand, Netherlands, Japan, Sweden, Switzerland, Ukraine, and Zambia. There are probably some in Austria, Belarus, Kazakhstan, Latvia, Lithuania, Russia, Siberia, and Slovakia. Also, during recent wars Mierzejewskis have died or been killed in Korea, Marshall Islands, Philippines, and Russia.

Early Immigrants

At the Ellis Island website 88 Mierzejewska/i and 82 Mirzejewska/i immigrants are listed, but because of spelling variations the total is closer to 550 than the above 170. Many returned to Polska.

The 1900 federal census states Felix, wife Pauline, and daughter Wanda Mierzejewski of Milwaukee, WI, arrived in 1880. It appears they lived in Maryland before moving to Milwaukee.

The 1903 naturalization record of Julius Julian Mierzejewski of Milwaukee, WI, lists April 1881 as his arrival date. He lived in St. Joseph, MO, before moving to Milwaukee. His son Julian was born in St. Joseph in 1887.

Agniska and Leonhard Mierzcjewski arrived at Baltimore, MD, 29 January 1883, on the ship “Amerika”.

Auguste Mierajewski [female] arrived at Baltimore, MD, 20 June 1883 on the ship “Herman”.

Jozef Mierzyeski, wife Antonina, and children Stephen and Pelagia, arrived 4 May 1887 at Baltimore, MD, on the “Hermann”. The family lived in south western Pennsylvania and used the name Majesky, but the original spelling was Mierzejewski.

The above arrivals follow the pattern of the earliest Polish immigrants coming from the German Partition, and note that they all arrived at the port of Baltimore, not New York.
On the 1920 Federal Census Peter Mierzejewski of Milwaukee stated his age was 66, making him the oldest Mierzejewski in the US (born about 1854 in Poland). On the 1930 Census Damazy Mierzejewski of Milwaukee said his age was 76, making his Polish birth year also about 1854.

On the 1920 Federal Census the age of Casimir Mierzejewski of Milwaukee, WI, is listed as 35 and born in Maryland, making him the earliest known Mierzejewski born in the USA (about 1885). Agnes Mierzejewski, who died in 1890 in Milwaukee, was born in Maryland (Baltimore) in 1886.

Anthony T. Mierzejewski wrote on his 1942 Draft Registration Card
2 August 1886 as his Pittsburgh, PA birth date.

Other early arrivals were Franciszek (Frank Baker) Mierzejewski and wife Anna Milewska and family who lived in Watervliet, NY, about 1890. In 1889 in Baltimore, MD, John Frank Mierzejewski was born. In 1890 an Aleksander Mierzejewski arrived at the Port of NY. This time period is one generation earlier than the period of the "great immigration" which lasted until WWI (1915).

Where We Live

The top eight Mierzejewski states (in alphabetical order) are Connecticut, Massachusetts, Michigan, New Jersey, New York, Ohio, Pennsylvania, and Wisconsin. Connecticut, the state with the highest percentage of Poles, is probably the state with the highest percentage of Mierzejewskis.

Mierzejewskis are known to have resided in 47 of the 50 United States, leaving only Hawaii, Maine, and Nevada. A Mierzejewski who was killed in WW II is buried in HI, a daughter of a Mierzejewski lived and died in ME, and a granddaughter of a Mierzejewski lives in NV.

The top six US Mierzejewski cities have traditionally been (in alphabetical order) Cleveland, OH, Meriden, CT, Milwaukee, WI, New Britain, CT, Pittsfield, MA, and Toledo/Rossford, OH. The descendants of the original immigrants have now spread out to suburbia and the rest of the country. 

There were about 350 publicly listed Mierzejewski [land line] telephone numbers in the US as of a few years ago.
