Mexican family that came from Guadalajara, Jalisco in Mexico. The name traces its roots to the Spanish word islands. The name was changed from Islas to Yslas in 1904 when our first relative came to the United States. The reason for the changing of the name from an I to a Y was to make it sound more American and Yslas left Mexico after running away with a politically connected Ranchero's soon to be bride.

The safeguarding of Earth and other worlds from biological cross-contamination (i.e. billionaires with too much time on their hands).

Also known as “planetary protection.” Planetary protection / quarantine “reflects both the unknown nature of the space environment and the desire of the scientific community to preserve the pristine nature of celestial bodies until they can be studied in detail.”

There are two types of interplanetary contamination. Forward contamination is the transfer of viable organisms from Earth to another celestial body. Back contamination is the transfer of extraterrestrial organisms, if such exist, back to the Earth's biosphere.
