    J. Mickelson and Rosalia Sonoski —> Josef Wilhelm Michelsson and Rosalie Tarnoffsky.

    I think Rosalie’s father was Polish.

    I think you should split his 4 grandparents to have a better view

  3. cwm85 says:

    If he is 75 percent latin, Portuguese, Italian. How did he end up with Mickelson as a surname? Is it Swedish?

  4. madman says:

    Phil’s paternal great-great-grandmother was Rosalia Sonoski. Sonoski is definitley not a Swedish surname. I have not found its exact origins, but most people with the surname that was born outside the US was from Poland, so Phil most likely has Polish ancestry.

    I have found a person named Rosa Sonoski that was born in Poland in the 1800’s, but no indication that they would be the same person or in any way connected.

    I know that the given name is not very indicative of a person’s ancestry, but Rosalia is not a very common name among Swedes. Perhaps it is evidence that she was born somewhere else (likely Poland) than Sweden, rather than having a distant Polish ancestor. If that is the case, it would make Phil 6.25% Polish.

    Also: tag Azorean and Finland-Swedish/Swedish-Finnish
