I recognize you posted many years ago, but I am a "Brook." Apparently my grandfather, Alfred (or on some records, Alphlord) Borucki changed his name at some point to Brook. Another part of the Chicago Borucki's changed their last names to Winters. I don't know what caused the name changes, but apparently my maiden name, Brook, was derived from the original Polish name, Borucki. Are you related to the Borucki family?
