Kosober
Kosober is a surname of Ashkenazi Jewish origin. It is believed to be a topographic surname, derived from the place name Kosobudy, Kosobądź, or similar variations, which are villages or settlements in Poland. The name likely originated with someone who came from or was associated with one of these locations. The root "Kos-" likely refers to "kosa" meaning scythe in Polish and other Slavic languages, perhaps referring to a place where scythes were used or manufactured. The suffix "-ober" is a common Germanic addition to surnames, particularly in regions with a significant Yiddish-speaking population. The name may also have been subject to variations in spelling and pronunciation as individuals migrated and settled in different regions. The surname is relatively uncommon.
