Hi. I just started researching some of my relatives. All I know so far is that my great grandfather's name was Rudolph Supancic and he was born in Austria. He immigrated to New York City around 1900. He married a woman named Elizabeth. I know he was in military in Austria and became a tailor in New York City making uniforms. Don't know much more. Any next steps would be greatly appreciated. I know he also resided at 462 West 126th St. through around 1920.
Let me know.
