The Danko Surname Study

I am pleased to announce the launch of the Danko Surname Study.

The Danko Surname Study is designed to study the relationships among those with the surname Danko and its variants.

The study is comprised of two projects:

The Danko Genealogy Project: a one-name study to document the genealogy of those with Danko ancestors; and
The Danko DNA Project: a Y-DNA study to analyze the genetic relationships of men with the Danko surname.

According to Kazimierz Rymut (Rymut, Kazimierz. 2003. Dictionary of surnames in current use in Poland at the beginning of the 21st century. Chicago, IL: Polish Genealogical Society of America.), in Poland at the beginning of the 21st century, the distribution of the Dańko surname and its variants included:

  • Danco – 1
  • Danko – 75
  • Dańka – 16
  • Dańko – 998

The surname distribution in Poland is shown on the following maps:

  1. Danko Wendy says:

    I came across your web site by accident, but then again… I never really believed in coincidences. My name is Wendy Danko and I am the granddaughter of Eugeniusz Dańko, who was born in Piaski (Poland), a town near Swidnik, 1922. He did on August 11 2006. One of his last wishes was to find his brothers, but he was too old and too ill to do this himself. He left me a letter from his mother , with the address of his brother Kazimierz Dańko, who was a Polish soldier in the UK during WWII. The letter was written at the end of the ’40s. My grandfather had at least one more brother, and one sister. His sister is the only one who stayed in Poland during and after WWII, and my father found her in 1986 in Swidnik. She too had lost contact with her relatives. My grandfather’s father was named Joseph, and I know my parents have a copy of by grandfather’s birth certificate with more details. I would love to find out whether you came across any of my relatives. We might even be related ourselves…In any case I’m more than willing to share the story of my family history with you and contribute to your research. Hope to hear from you soon…

  6. Rod Viquez says:

    My great grandmother was Mary Danko. She Was from Geraltov Slovakia. Think it’s only about 30 miles to the Polish border from there

  7. Hi Steven. My father was Frank Danko of Lauder Manitoba. My cousin was the musician Rick Danko. We have many many male relatives living in Ontario, one in USA and my brother in B C. Our grandfather would not tell us about ‘the old country’ although he married a woman from Kiev grandfather claimed to be Polish. His musical ability continues today among many of his grandchildren and great grandchildren. Our grandparents came to Canada at the early 1900’s obviously to escape Communism.
    Grandfather called himself Joseph but we have no idea where he came from in Europe. He spoke several languages including Hungarian polish Ukrainian English
    Any help would be appreciated.
