Etymology
No secure dictionary etymology is established for Sustaita. Its form looks Hispanic, and surnames of this shape are often tied to a place-name, a nickname, or an older family name that has shifted in spelling over time. The ending and overall structure do not point clearly to a single standard Spanish word, so the safest explanation is that it is an inherited surname of uncertain local or regional origin.
History
Sustaita is found mainly in Hispanic communities, especially in the United States, where it is uncommon but not rare. The surname may reflect a family line that preserved a localized Spanish spelling, possibly with variation in older records. Because the name is not well documented in standard onomastic references, its early history remains obscure.
