There were two Gennaro Fabricatores, father and son, making guitars in Naples during the first half of the century: Gennaro I (c.1770–1844) and Gennaro II (1800–1853). From the address on the label of the 1813 Gennaro Fabricatore guitar in the Austin-Marie Collection, we can conclude this guitar was made by the elder of the two, Gennaro I.
