PROVO, Utah, May 1 /PRNewswire/ -- To celebrate Cinco de Mayo, Ancestry.com, the world's largest online resource for family history, today announced the release of the first and only online collection of border crossing records for individuals who crossed the U.S. - Mexico border between 1903 and 1957. This new collection, which includes more than 3.5 million names, is the latest addition to Ancestry.com's Immigration Records Collection, which also includes the largest online collection of U.S. ship passenger list records featuring more than 100 million names from 1820 to 1960.

These border crossing records primarily document early 20th-century Mexican immigration to the United States. During the first 30 years of the 1900s, more than 1 million Mexicans immigrated to the United States as a result of the Mexican Revolution in 1910, job opportunities during WWI and U.S. agricultural advances.

"There are unique and untold stories waiting to be discovered about the American southwest and Mexico," said Megan Smolenyak, Chief Family Historian for Ancestry.com. "This collection represents a significant opportunity for Mexican-Americans to discover their family's footsteps to the United States and for everyone to celebrate Mexican contributions to American culture. Interestingly, the records cut across several ethnicities. For instance, those of French, Russian and Chinese heritage may be surprised to find their ancestors in this collection."

These records contain insightful clues into a family's past, such as names and birthdates of travelers, names of friends or family in Mexico or the United States, as well as some signatures. This collection will be an especially useful tool for individuals whose ancestors arrived from Mexico between 1908 and 1957, as the most complete records were kept during this time period. Many of these border crossing records also include passport-type photos that were attached to the original documents.

Ancestry.com transcribed the names in the collection from more than 3 million documents. The records were culled from 24 land ports of entry from California to Texas. Among the busiest ports of entry were Laredo, Brownsville and El Paso, Texas; Nogales, Arizona; and San Ysidro, California.

Users can build their family tree on Ancestry.com, upload photos and stories and invite family members to participate -- all for free. Right now, Ancestry.com is also offering free three-day access to all premium records.
