Submitted Surname Revision History

Derives from a Slavic surname and originates from western Ukraine. The term was initially used to describe either people from the East (Polish name) or people from the South (Ukrainian name). Jastremski is derived from the word jastrom, meaning 'easterner'.

Another theory suggests that Jastremski comes from the Czech word jasno meaning “light” or “bright”; this was adopted first by the family which then used “stremski” or “stremský” as the surname.
