Jules Francois Bourgoyne & Cecile Adelaide Tullier

Jules Francois Bourgoyne, my husband's third great-grandfather, was born c. 1798 in Rouen, Seine-Maritime, Haute-Normandie, France, the son of Francois Bourgoyne and Julie Lefevre.  He married Cecile Adelaide Tullier, the daughter of Jean Charles Tullier and Rose Adelaide Daigle, on 07 August 1824 in Point Coupee Parish, Louisiana.  Cecile was born 23 June 1803 in Louisiana.  

When did Jules Francois Bourgoyne arrive in America?  Obviously it was before his wedding date in 1824.  Did he travel from France alone, as an adult, or was he with his parents?  The passenger ship list would provide me with possible answers, if I could locate it.  

Jules Francois and his wife eventually settled in West Baton Rouge Parish, Louisiana.  They had five known children:  Sons- Jules Adolphe (my husband's great-great grandfather), Theophile and Marcel Forestin; Daughters- Juliene Pourpore and Marie Celestine.  

Jules Francois was about 40 years old at the time of his death on 14 April 1838.  What was the nature of his death at such a young age?  Was it an accidental death, or did illness claim his life?  Regardless of the circumstances, his wife Cecile was left alone with five children to raise on her own.  Unfortunately, a year later, on 22 April 1839, Cecile died.  She was only 36 years old.  At that time, their oldest child, Juliene Pourpore, was 14 years old and their youngest, Marcel Forestin, was only 5 years old.  According to family history, the young orphaned children were taken in by Joseph (Josime) Tullier and his wife.  Probate record #298 filed in West Baton Rouge Parish shows that Joseph Tullier was appointed legal guardian of the children.  When the 1850 census of West Baton Rouge Parish was taken, Theophile and Forestin were still residing with Josime Tullier, and they were listed as "planters" or laborers in his household.  Jules Adolphe, who was by then a grown young man, was living with his sister, Juliene, who was married to Faustin LeBlanc. I suspect that Marie Celestine Bourgoyne was also married by 1850, as she would have been about 19 years old by then.
