A very prestigious Mediterranean family tree where wealth and old money passes down the line. Formosa's are usually haunted by their own vanity.

Today, most Formosans reside in Canada, Australia, and the United Kingdom but can be found all over the world.

Formosa also means "beautiful" in Portuguese.
