Susskind (German Süßkind "sweet child", variants Suskind, Suskin, Siskind, Ziskind, Ziskin, Siskin, etc.)
Süsskind in the German medieval period was a given name, not a surname, specifically recorded as carried by Jews since the early 13th century.
Süsskind, the Jew of Trimberg (Middle High German Sueskint der Jude von Trimperg) is one of the minnesingers whose work is compiled in the early-14th-century Codex Manesse.
There is also a Jewish motif in V.2, where the poet proclaims his intention to leave the courtly sphere and live humbly "in the manner of old Jews", besides possible allusions to Hebrew prayers in I.3.
[3] Karl Fedor Süsskind, born in Dresden in 1843, introduced the surname "Süssekind" in Brazil.
