Francois Duguesclin Beaudouin was born in Port-Salut, Haiti on September 21,1925. He was the first born of three children from the marriage of DestinBeaudouin and Emma Gerard. He attended Primary and Secondary Schools in Cayes, Haiti. After completing High School, he returned to Port-Salut where he established himself as a successful businessman and tailor. He always had a knack for business.

Duguesclin married his wife, Adrienne Fortin, at the age of 29. They have six children: Adeline, Jean, Robert, Marie, Naromie, and Callixte. He immigrated to the United States in 1965. He then sent for his wife and his first-born son, Jean, in 1968. The other children came to join him in the United States later; the last one to arrive was Robert, in 1981. In America, he worked at St. Luke's Roosevelt Hospital for many years, until he retired in 1990. After retirement, he travelled back and forth between New York and Haiti - until the devastating earthquake in Haiti, in 2010.

He passed away after a brief illness at Montefiore Hospital, in the Bronx, on July 8, 2021, at 11:45 AM.

Throughout his life, Duguesclin was a man of integrity. He believed in hard work, and in doing the right things. He cared deeply about public opinion. He was a very generous man; he believed in helping those who are less fortunate. He did not like to be taken advantage of. He loved his wife of nearly sixty-seven years, and cared deeply for his children. He was a strict disciplinarian, and wanted the best for his family; he had very high expectations for his children. Above all, he did not want his children to embarrass him in front of society.

Duguesclin was preceded in death by four siblings - Eveline and Rigaud, from his father's first marriage; and Marie Carmel and Hilaire, from his father's second marriage.

He is survived by his wife, his six children, six half-siblings, several grand-children, great-grand-children, as well as a long list of cousins, nephews,nieces, and friends in the United States, Canada, and Haiti.
