I do not know of a Claire Lesko, but if the Agnes Lesko you mentioned was married to Martin Wanczyk, their son Walter Wanczyk married my grandmother's sister, Bernice Kostek, making Walter and Bernice's children my father's first cousins. If this information matches what you have, I can E-mail you the names of Bernice's descendants, so you can add them to your family tree, if you don't already have the information.
Your article sounds great, but I am not a member of the Polish Genealogical Society of Massachusetts. Despite that, I also wrote a piece for them, entitled The Story in the Stones, which focuses on ethnicity. It is in the October 2006 issue of Biuletyn Korzenie.FirstKahn@AOL.com
