named for Jonas Bronck, who settled there in 1641.
Jonas Bronck, who arrived at New Amsterdam in 1639, and whose name is perpetuated in Bronx Borough, Bronx Park, Bronxville -- in New York -- was a Scandinavian, in all probability a Dane and originally, as it seems, from Thorshavn, Faroe Islands, where his father was a pastor in the Lutheran Church. Faroe then belonged to Denmark-Norway and had been settled by Norwegians. The official language of the island in Bronck's days was Danish. ... Bronck may have been a Swede if we judge by the name alone for the name of Brunke is well known in Sweden. [John Oluf Evjen, "Scandinavian immigrants in New York, 1630-1674," Minneapolis, 1916]
