Vicente Tatay was a guitar maker in Valencia who opened his workshop in 1889 (or 99? I have seen both as foundation dates and his father may have opened a workshop called Tatay in 1861). He took his sons on to help him, (he had 8 sons and 1 daughter), and then more staff until the workshop was transformed into a factory, continuing to grown into a major factory producing some 40,000 instruments a year. Vicente Tatay retired in 1942, and the firm was taken over by 7 of his sons, (One, Andres Tatay Tomas, had emigrated to the US and started his own workshop in New York), who renamed it "Hijos de (Children of) Vicente Tatay". Vincente senior died in 1950 and another of the sons, Vincente jnr. left to start his own workshop called Vicente Tatay Tomas. 

The main factory closed in 1979 but the sons who had left both kept going with the US branch going on through grandsons and finally closing in 2003, and the Valencia offshoot having Vincente jnr, finishing in 1999. But the story doesn't end there as in 1989 another grandson Jose Tatay Cuenca, (a son of Jose Tatay), opened his workshop on Calle Zapadores 31, Valencia and is still in business and using the family name. 

When the main factory was in operation, in addition to Guitars they made all kinds of Spanish folk instruments like Bandurrias, Lauds and Guitarron/Ukuleles. I don't know if any of the offshoot workshops produced any Ukuleles?
