The Mentkowski Family
Prepared and researched by Margaret Odrowaz-Sypniewska, B.F.A


Mentkowski, Mentowski, and Metowski might all refer to place names in Poland(?), since a few arms books mention that it MAY have had a noble tradition. However, I could not find a coat of arms in Herby Rodow Polskich by Paszkiewicz and Kulczycki, Orbis Books (London) ltd., 1990. Thus I believe that it might have been an ancient noble name which no longer produced male heirs?

The only name that appeared as a noble was Mankowski, which belongs to three clans:

  1. Jastzebiec
  2. Pwawdzie
  3. Zaremba




According to Sl~ownik Nazwisk there are only 14 Mentkowski's in Poland:


Joseph Mentkowski (Josef on tombstone) was born March 5, 1858/*60 and died in April 21, 1928 at age *68/70. Joseph married Mary Plotkowski in Poland. Josef was buried in St. Stanislas Polish Cemetary, Allegheny County, Pennsylvania, on April 25, 1928 (*death certificate and tombstone). At the time of his death, he was living at 3200 Dobson Street in Pisttsburg, Pennsylvania.

Joseph had a brother that lived in Niagara Falls.
