This name can also be of West Frisian origin, in which case it most likely comes from Duco, which is best known for being the name of the Frisian freedom fighter Doecke "Duco" van Martena (1530-1605). Doecke is an archaic spelling of Doeke, which is a diminutive of Doede.Out of all the masculine names that are ultimately derived from Doede, Duco is the most common today. Even more so than Duuk, which is a fairly recent (1960s) addition.Also note that whilst Duke is best known as an English name, it can also be a West Frisian name, in which case it is a variant of the aforementioned Doeke. The Frisian name Duke is pretty rare, but at least it has been around longer than Duuk.Sources: - https://www.vernoeming.nl/voornaam/duuk (in Dutch) - Doecke "Duco" van Martena (1530-1605): https://nl.wikipedia.org/wiki/Doecke_Martena (in Dutch) - submitted entries of Doede, Doeke, Duco and Duke (each of which have their own sources)
