The founder of the Negroni Family in Puerto Rico was Antoine Francois de Negroni de San Colombano (Castle of San Colombano, born 1794, died in Yauco, 2 April 1861).
Upon his arrival in 1822 to Puerto Rico he changed his name to Antonio Francisco Negroni Mattei. Although his passport indicates that he was born in 1794. Antoine Francois established the Negroni Family in Puerto Rico.
He married three times. His first marriage was 18 May 1826 in Yauco to Rita Rodr�guez de la Seda y L�pez de Victoria (born in Yauco, 1808, died. in Yauco, 12 December 1839). She was the daughter of Pascual Rodr�guez de la Seda y L�pez de Victoria (Yauco, 1756-Yauco, 22 January 1823), who had been the mayor of Yauco 1811-1817 and of Maria Luisa L�pez de Victoria (Yauco, 1772-Yauco, 18 November 1850).
[My family connection is with--Rita Rodriquez de la Seda Lopez de Victoria.] She was Antonio Francisco Negroni Mattei 1st wife.
On the 1st of June 1822 Antonio Francisco received his Letter of Naturalization. He rapidly integrated into the political and military elite of Puerto Rico. Eight years later he was appointed commander of the Yauco Urban Militia Corps and serving in that capacity from 1830 to 1840. In 1838 he was appointed major of Yauco. He served as major from 1838 to 1843 and again in 1846. In 1848 he was appointed by the Captain General of Puerto Rico as Teniente a guerra (supreme civil and military authority in the town of Yauco). From 1847 to his death in 1861, he was a corresponding member of the prestigious Economic Society of Friends of the Country), an organization devoted to the improvement of the Puerto Rico economy.
He devoted his life to agriculture and in 1840 established his plantation (hacienda) Florida. This plantation was built on land formerly owned by the Pacheco de Matos family. Six year later this plantation was Yauco's largest with an area of approximately 970 acres), worked by 38 slaves and having a declared capital of 23,661pesos ( note that the Governor and Captain General of Puerto Rico had a monthly salary of 183 pesos! By 1851, Antonio Francisco had 41 slaves.
In 1850 Puerto Rico's first irrigation system was built by Antonio Francisco. In 1852 he sold the plantation to Juan Maria Antongiori. Shortly thereafter Antonio Francisco founded another sugar plantation, hacienda San Colombano, in the Barrio Playa of the town of Guayanilla.
The cholera epidemic of 1856 was a severe blow to Antonio Francisco's agricultural enterprises because it killed most of his slaves. In December 1862 San Colombano was sold to the firm Tirado & Labarthe.
Antonio Francisco was also a coffee grower and his coffee plantation La Fortuna in Barrio Indiera Alta in Maricao was inherited by his daughter Maria Luisa and from there passed into the Lluch Family by marriage.
Two principal residences were owned by Antonio Francisco -- Casa Agostini -- Don Antonio Francisco Negroni Mattei's daughter --Maria Victoria Negroni Rodr�guez (1838-1900) who married Ignacio Agostini and later inherited this residence-- and a two story masonry country home in his hacienda La Florida which allegedly was one of the finest in Puerto Rico.
