It is well derived from a female given name and means 'of Sarah'. It could be taken by a son, the husband or even a son-in-law of some Sarah.It appears in my book "A dictionary of Jewish surnames from the Russian Empire" (2008):Sorotskin (Vitebsk), Sorochkin (Minsk, Polotsk, Nevel', Mstislavl', Chernigov)from the given name Sorochka, a pet form of Sora (Sore in the Lithuanian Yiddish) 'Sarah'.As you can see, the area where bearers were living at the turn of the 20th century corresponds to eastern Belorussia where numerous matronymic surnames were created ending in the Russian/Belarusian possessive suffix -in. This area is very far from Serock.Best,Alexander Beider
I was recently asked if the Jewish surname Sorotzkin is a matronym meaning "descendant of Sarah," or geonym derived from the town Serotzk/Serock in Poland.
