Bear Climbing On The Tree

In Russian and other Slavic languages, the word for bear, "Medved" (медведь), and variants or derivatives such as Medvedev are common surnames.
The Irish family name "McMahon" means "Son of Bear" in Irish.
In East European Jewish communities, the name "Ber" (בער) — Yiddish cognate of "Bear" — has been attested as a common male first name, at least since the 18th century, and was among others the name of several prominent Rabbis. The Yiddish "Ber" is still in use among Orthodox Jewish communities in Israel, the US and other countries.
With the transition from Yiddish to Hebrew under the influence of Zionism, the Hebrew word for "bear", "Dov" (דב), was taken up in contemporary Israel and is at present among the commonly used male first names in that country.
