Steve,
After coming across some recent information about the Dlugokenski family, I have found that the family name in Poland used to be Dlugokecki. In fact, my great great grandparents were Zigmund and Eva Dlugokenski. Hope this helps you out... Check out
http://www.geocities.com/ginanne17 for more information. I update the site every time I find new info. There should be a new update within the next couple of days regarding Zigmund's baptism. Can you help us out with any missing info, ie. brothers and sisters of Zigmund.
Thanks
Gin Harnischfeger
