Ten generations before I was born, and for at least three generations before that, my French-speaking ancestors settled in Port Royal on the Annapolis River.
They probably arrived as colonizers in 1603. That’s when France’s King Henri IV set up “La Cadie” between the 40th and 46th parallels south of the Saint Lawrence River. For a good idea of how they lived, visit the Port-Royal National Historic Site.
Just before, or just after, the birth of François Allard III, his parents left the region for Quebec.
I imagine they refused to swear allegiance to the British monarch.
For at least three generations, French settlers like them fought with local Mi’kmaq people against British settlers in New England. Throughout the years, many cross-border conflicts and trade ship privateering occurred. The worse early incident led to Port Royal’s destruction by fire in 1613. It was rebuilt and skirmishes continued for a century, with the French and Mi’kmaq remaining strong.
Siege of Port Royal
The siege of Port Royal in 1710 marked the beginning of the end of French dominance in the region.
On October 5, 1,880 British and New England soldiers arrived at Goat Island just south of Port Royal in five warships with accompanying transport and bomb galleys. First, they blockaded supplies, food and water from getting into the town. Then they began moving men and equipment into the Annapolis River to get ready to attack the fort. One transport capsized killing 23 men. After that, they moved more carefully, landing safely.
Canons attacked the fort for a week. By the end of the day on October 12, the French gave up. The terms of surrender were signed the following day.
According to the University of Moncton researcher N.E.C. Griffiths, surrender terms said:
that the Inhabitants within Cannon shot of the Fort of Port Royal, shall remain upon their estates, with their Corn, Cattle and Furniture, During two years in case they are not Desirous to go before, they taking the Oaths of Allegiance & Fidelity to Her Sacred Majesty of Great Britain.” 
Over the next three years, Port Royal became Annapolis Royal and La Cadie became Nova Scotia. Sometime during this period, my family shed their maritime roots for landlubber status.
1714 Acadian Census
The 1714 Acadian Census shows a family headed by François Allard living in Port Royal with his wife, one son and two daughters. If these are my ancestors, François was either a second son who came later or his birthdate is wrong.
More likely this was a different family.
According to my grandmother’s records, my nine times great grandfather Jean-Baptiste Allard and his wife Anne Elisabeth Pageau had François III on February 3, 1719.
It’s hard to figure out why her records show him as the third person to hold the name “François” with his father clearly identified as Jean Baptiste. She does show his grandfather as Jean François but his great grandfather’s name was Jacques. He doesn’t get it from the other side for sure. The men in Anne Elisabeth’s family were Thomases going back at least two generations.
When did they move to Quebec?
My grandmother’s notes show François III’s birthplace as Port Royal, although I found a family tree online that shows a man with the same name born to parents with the same names in Charlesbourg, Quebec.
Either way, by the time François III got married in November 1741, he and his wife Barbe Louise Bergevin definitely lived in Charlesbourg, Quebec. Their daughter, Marie Louise Allard, would be born on November 3, 1742, at Notre Dame de Quebec. Any links to the shores of the Annapolis River were lost forever.
Meanwhile, Acadians in Nova Scotia refused to swear allegiance to the Queen of Britain. Wars continued in the region until 1758. The expulsion of the Acadians, which began in 1755 and continued until the British Conquest, led to Longfellow’s famous poem about Evangeline and Gabriel.
By then, my ancestors were well-established in Quebec.
We have none of the deported Acadians in the family; only people who originally settled La Cadie.
