Burciaga
A surname of uncertain Spanish/Mexican origin, most likely tied to a place name or local nickname rather than a common occupation or patronymic.
The #6,909 most common surname in the United States (2010 Census) — about 1 in every 63,580 Americans shares it.
Etymology
Burciaga appears to be a Spanish-language surname, but its exact origin is not securely established in standard reference works. It is usually treated as either locational or descriptive, formed from a regional place name or a local word that has not been fully traced in later surname dictionaries. The ending -aga is common in Iberian place-based surnames, which supports a toponymic explanation, but the first element remains unclear.
History
The surname is most strongly associated today with Mexico and with Mexican-American families in the United States. Like many Spanish surnames that spread through colonial-era migration and later movement across North America, it is now found chiefly in the U.S. Southwest and in Mexican communities. Because the name is relatively uncommon, its older documentary trail is thin and the earliest origin remains uncertain.

Fun fact
The surname is uncommon enough that modern family lines can sometimes be traced more easily through parish and civil records than through surname dictionaries.
