Pedro de Alberni was born on January 30, 1747, to a noble and wealthy family of Tortosa, Catalonia, Spain. His father, Jaume d'Alberní i Antolí, was notary public and Honourable Citizen of Barcelona who had married Maria Inés Teixidor on June 24, 1728. The couple had five sons and two daughters.In accordance to Catalan civil law, the oldest brother, Josep Antoni, was named heir to the Alberni estate, including the right to use the title of notary public. The remaining siblings received a small amount of money. For this reason, the rest of the brothers joined the military service. One brother, Gerònim, went to the Regiment of Córdoba; the other two, Joan Bautista and Jaume Pascual, joined the Foreign Volunteer Regiment. One of the sisters became a nun. Pedro joined Spain's Second Regiment of the Light Infantry on July 17, 1762 to fight as a cadet in the campaign of Portugal during the Seven Years' War when he was only fifteen years old.
Alberni died of dropsy at the age of 55 in Monterey, Alta California, on March 11, 1802. He was buried at the Royal Chapel of San Carlos in Monterey, California. Today, his remains probably lie under the highway that was built nearby, because his tomb was never found. Alberni's will, dated December 16, 1801, leaves everything to his wife, Juana Vélez, a native of Tepic, México. The only daughter they had predeceased him. Sergeant Joaquín Tico from the Volunteers of Catalonia was executor of his will.
