New Discoveries About Damian Niedzialkowski / Damian Cosky

After finding Damian Niedzialkowski’s Naturalization Records, I discovered that, during the Naturalization Process, Damian changed his name to Damian Cosky.

This surname change was not unusual. My Chmielewski relatives changed their surname to Meleski, and my Dziura relatives changed their surname to Dziurzynski. Other Niedzialkowski relatives changed their surnames to Niedzialkoski, Niedzial, and Newman. I’ve also learned that other Niedzialkowskis changed their surname to Sunday (a translation of the name).

The surname change from Niedzialkowski to Cosky revealed why Damian seemed to disappear from the Worcester, Massachusetts records after his naturalization, leading me to speculate that he and his family moved away from Worcester. Knowing that he changed his name, I’ve been able to determine that he and his wife remained in Worcester, appearing with the surname Coski in City Directories and other records.

Information from Damian’s naturalization records provides clues for additional research, including clues to immigration records, Polish church records, Massachusetts vital records, Massachusetts land records, and Massachusetts court records. I still don’t know if or how Damian Niedzialkowski is related to me, but this additional information gives me hope that I’ll be able to discover the answer to these questions.
