I too have Vaneks in Chicago with no connection. William Vanek, born 19 Sept 1893, died 31 May 1919, supposedly in Chicago, supposedly in a railroad accident. Don't know his birthplace, Mother's name was Agnes. I don't know her maiden name. A relative told me William's father was Martin, but no proof. William was married to Hermena Fiala, and had 2 daughters. He is buried in Moberly, MO. Any info would be appreciated!
