In the meantime, Jean worked for his father in the Sebastopol Plantation until his early 20s. In his late 20s, he moved to Mexico and finally settled down at the port of Tampico (Eureka community) along with his uncle, Aristide Romain. Jean was also known as "John" in Louisiana and later as "Juan" in Tampico where, along with his uncle, he worked as a tailor for the wide foreign community which had settled in Tampico due to the oil boom. Jean married Mrs. Carmen Castelló Caimares, cousin of Carmen Romero Rubio Castello, wife of the Mexican President Porfirio Díaz. Because of the untimely death of his youngest brother, Ignace François, aged one year old, Jean decided to extend the Ignatius line, so his first son was named Ignacio Francisco (1877–1933). After him came Juan Melquiades, Julio Fructuoso (father of Mons. Arturo Szymanski , Bishop of Tampico and Honorary Archbishop of San Luis Potosí), Jose Amado and Jose Ramon Blas. Jean and Carmen also had twins but they did not survive. Jose Amado drowned at the age of 19 during Regatta festival. Jean's grandson, the son of Ignacio Francisco, Ignacio Sabás Szymanski Rodríguez (1905–1998) lived in San Antonio, Texas, until he was 21. After graduation from the La Salle Brothers College as a book keeper, he returned to Mexico to work for the Sinclair Oil Corporation and, after World War II, he worked for Mexicana de Aviación as supplies director as well as president of the Airlines Association of the Americas until his retirement. Today, the Ignatius name continues with Ignacio Francisco Szymanski Morales (1935), Ignacio Alejandro Szymanski Chávez (1961) and Ignacio Francisco Szymanski Garbuno (2000)
