My mother's birth name was Aniela Swientek - changed it to Nancy Bray - their branch of the family changed their names from Swientek (got the spelling from Mom) to Bray some time in the 1920s. My father's Mother was named Iverina. My maternal Grandmother was Lottie who came over from Poland in 1904 and married Albert Swientek who was born in the USA but as far as I know his parent's came from Poland.
Are these the people you're looking for? If so, and Nancy is the grandmother of your husband, you'd be married to one of my nephews. If not, good luck with your hunt. P.S. there was an Anna on my Dad's side of the family.
