I am just now finding this thread and can hopefully shed some more light on this complicated relationship between Vincent and Helen.
Helen Grezgorek was married once BEFORE her marriage to Vincent Kasiorkiewicz on November 10, 1919. Helen was my great-grandmother. Helen was married to Michal, (Michael), GAJEWICZ. With Michal, Helen had two children... Raymond Bernard Gajewicz, (my paternal grandfather), and Edmund Gajewicz. Michal died on April 11,1919 from a surgical accident. He was 25 at the time. Helen remarried that same year to Vincent Kasiorkiewicz. Vincent and Helen subsequently had four children: Sylvester, (Uncle Sally), Daniel, (Uncle Danny), Clara, and Lawrence, (Uncle Larry).
My grandfather casually went by the last name, "Gibbs". He never officially changed his last name from Gajewicz. He told me once that he just never got around to it. Long after he and grandma died, many people still thought their last name was, "Gibbs", and grandpa's nickname was, "Gibby", so it must have seemed to make sense. His obituary, I believe, had to read, "Raymond Gibby Gibbs Gajewicz", just so his friends knew he had died. Uncle Eddie, grandpa's brother, legally changed his name from Gajewicz to ,"Guy".
I was born in 1963 and I knew my great-grandmother and all of the great aunts and uncles mentioned here and have information on them all if there are any family members interested.
Hope this helps.
