Your lineage is correct from David on up to Michel, and descends through the Wedgeport, NS branch of the family.
You are correct to guess that Pierre (husband of Anne Hébert) was the Acadian exiled to the colonies. He can be found in the 1763 enumeration of the Acadians in Newtown, Maryland as a widower, with his children Marie-Josephe, Amand and Michel. Of these children, your next ancestor Michel returned to Nova Scotia, where he married Marguerite Pothier, daughter of Dominique Pothier and Anne Surette (according to their son Amable Boudreau) at Cap Sable on 10 Jan 1773. The majority of the Wedgeport Boudreaus descend from this couple, and had he not gone back there, your line of Boudreaus would have ended in Maryland.
On the other hand, Michel’s brother, Pierre Boudrot, died in Bonneuil-Matours, France in 1792, where he and his wife, Françoise Daigle had been exiled. As far as I know, Pierre and Françoise’s sons Benjamin and Paul are the ancestors of a small line of Boudrots in the region of Lauthiers, La Puye and Cenan, France, which I traced to 1927 in that area. After that marriage date, and well past the cutoff year of 1905 for research in the French Archives, I could not proceed further forward.
The next generations of Amable Boudreau (husband of Monique Duon), and their son, Joseph Boudreau (husband of Rosalie Richard) are also correct. This latter couple’s son, Remi, follows.
Your Jean-Remi (known solely as “Remi” the rest of his life), was baptised as Jean-Raymond in Wedgeport on 3 Sept 1842, and married twice, first in 1869 to Agnes Doucet, daughter of François-Ange Doucet and Catherine Robichaud, by whom were born 8 children. She died in 1883, and the following year, 1884, he remarried Madeleine Cottreau, daughter of Jacques Cottreau and Monique Comeau, by whom were born 7 more children, and among whom, your Jean-Eugene, was the oldest of the family, born at Wedgeport on 2 Aug 1885. While at home in Canada, he was known by the name “Eugene” in the 1891 (6y), 1901 (15y) and 1911 (25y) censuses. He also married twice: as “Jean-Eugene” in Wedgeport in 1911 with Lucie Surette, daughter of Jean-Baptiste Surette and Léonie Cottreau, who died the following year 1912 at 27 years of age. After her death, he removed to Massachusetts , where he married as “John Eugene” in East Boston in 1915 to Charlotte “White”, the daughter of François LeBlanc (AKA White) and Mathilda Boudreau of Ste-Anne du Ruisseau, NS. I had traced them down to Harry (1915) and James (1920) (he having just been born in the 1920 census of Boston). In September of that year, their father John E. returning to his fishing occupation, had contracted pneumonia on the vessel which he had been working, and when they put in at Canso, NS, he died there on 4 September 1920, aged 35y. He was buried back in Wedgeport five days later on 9 September. I would love to continue with this line down to you, but have no more information to add. Did your family go back to Canada or stay in Massachusetts? Did Charlotte ever remarry? Where did she and the boys settle? Would like to know Harry’s marriage and death data, as well as that of your grandfather, David, if possible.
As for Michel Boudrot and Michelle Aucoin (daughter of Martin Aucoin & possibly Barbe Minguet), nothing as to his origins has surfaced to the present.
