Luis Estrella, Telmo Estrella, or Luis Telmo Estrella, nor as Luis Paz, Telmo Paz, or Luis Telmo Paz.

Other surnames which started off as compounds of two or more surnames, but which merged into one single word, also exist. An example would be the surname Pazmiño, whose members are related to the Paz y Miño, as both descend from the "Paz Miño" family of five centuries ago.<!--This isn't a specific century!

In Portugal, a person's full name has a minimum legal length of two names (one given name and one family name from either parent) and a maximum of six names (two first names and four surnames – he
