Antonio L. Jayme was born on July 24, 1854, in what is now the district of
Jaro, Iloilo City. He was the eldest of seven children of Aguedo Gamboa Jayme and the former Sabina Lopez Ledesma. Jayme's family migrated to
Silay City,
Negros Occidental when he was still young. This occurred during a time when the Chinese
mestizos of Jaro and
Molo in
Panay Island were forced to search for better business opportunities aside from Iloilo's declining
textile industry, brought about by cheap imports from mainland
China. The promise of great reward afforded by the high price of world sugar constituted this preoccupation among Jaro's businessmen to settle in nearby Negros Island. Like the rest of the wave of immigrants, the Jaymes pursued
sugar-based
agriculture and transformed a tract of land into an
hacienda or plantation. As was common among the principalia in Negros, Jayme enjoyed an early education by crossing the Guimaras Strait to attend the
Seminario de Jaro, the Jaro Seminary. He was easily accommodated as his uncle on the paternal side, Fray Francisco Jayme (who tutored and raised Philippine patriot
Graciano Lopez-Jaena), was its first rector. From 1869 to 1871, Jayme studied philosophy and letters at Jaro which was still the most populated, most industrious and most prosperous province in the Philippines at that time. However, in a spirit of wanderlust and in search of better education, he left for
Manila to enroll at the
Colegio de San Juan de Letran in 1872. After completing his
segunda ensenanza (
Spanish, "secondary education"), he entered the
University of Santo Tomas, where he earned his
licenciado en jurisprudencia (equivalent to a
Bachelor of Laws) in October 1881. He was to become the first
Ilonggo lawyer to practice law in Negros during the Spanish colonial period in the Philippines. He subsequently entered public service as justice of the peace and judge of the Court of First Instance in the province. ==The Philippine Revolution and its aftermath==
