Pierre Arsenau est né vers 1646 ou 1650 en France.. Selon Stephen A. White, son lieu d'origine n'est pas connu. Son arrivé a Port-Royal semble être après le recensement de 1671. Il était un pilote côtier.
Vers 1672, Pierre collabora avec Jacques Bourgeois pour fonder la colonie Bourgeois, qui devint Beaubassin.
Pierre s'est marié deux fois. Il épousa Marguerite Dugas, fille de Abraham Dugas et de Marguerite Doucet, vers 1675. Le couple a eu deux fils: Pierre (n. vers 1676) et Abraham (n. vers 1678).
Le 26 sept 1683, Pierre a fait une déposition contre James Taylor de Boston qui était venu le voler ainsi que quelques autres de Port Royal.
Vers 1685, Pierre a convolé avec Marie Guérin, fille de François Guérin et d'Anne Blanchard, qui lui a donné six autres fils (Charles, Jacques, François, Claude (dit Ambroise), Augustin, et Abraham ) et une fille (Anne).
One of the largest Acadian families stems from one pioneer. Pierre Arsenau was born around 1646 or 1650 in France . According to Stephen A. White, his origins are not known. He likely arrived at Port-Royal Acadia (Annapolis Royal, Nova Scotia, Canada) after the Census of 1671. He was a coastal pilot.
Around 1672, Pierre collaborated with Jacques Bourgeois to found the colony Bourgeois, which became Beaubassin (Amherst, NS).
Pierre had two wives. He married Marguerite Dugas, daughter of Abraham Dugas and Marguerite Doucet, around 1675. The couple had two sons: Pierre (b. c1676) and Abraham (b. c1678).
On Sept 26, 1683, Pierre made a deposition against James Taylor of Boston that came and steal from him and others from Port Royal.
Around 1685, Pierre married Marie Guérin, daughter of François Guérin and Anne Blanchard, who gave birth to 6 more sons (Charles, Jacques, François, Claude (dit Ambroise), Augustin, and Abraham ) and a daughter (Anne).
During the time Pierre and Marie were raising their family, England and France were at war twice: 1687-1697 War of the League of Augsburg (King William’s War); and, 1702-1713 War of the Spanish Succession (Queen Anne’s War). During that time, the family would have witnessed the effects of two English raids at Beaubassin by Benjamin Church.
In 1696, Church's raid lasted 9 days. Once the English ships were seen, the inhabitants fled, carrying their more valuable possessions. Church recorded that the settlers’ ”cattle sheep, hogs, and dogs” were left ”lying dead about their houses, chopped and hacked with hatches". The church and some of the houses were also burnt.
The second raid took place in 1702:
"The Acadians were in arms and an indecisive skirmish ensued. After the Acadians retreated into the woods, Church and his men found that the inhabitants had removed as much of their household and farm goods as possible. Church set the buildings on fire... and killed about 100 cattle before leaving to return to Boston"

Birth and yDNA: Savard has his birth at about 1646 presumably because it is consistent with the 1671 Census where he is 40 years of age. Stephen White uses 1650 presumably because it is consistent with the later census of 1693, 1698, and 1700. We have put the date as 1646 to conform with Savard and to avoid confusion when searching the FTDNA site, which lists y-DNA results of Pierre Arsenault b. 1646 here.
Parents: Pierre's parents are unknown. Some believe Abraham and Marguerite Doucet are his parents, but evidence supporting this has not been found.
2nd Marriage. Minor discrepancy. Stephen White's DGFA p 23 lists marriage 'before 1686' (presumably because they are together in the 1686 census), but, his 37 familles paper lists it as 'around 1685'.

RESIDENCES: LE REVEIL ACADIEN; vol. XIII, no. 2 (May 1997) ; p. 50. Followup information from F. Rene' PERRON of LES A MITIE'S ACADIENNES. A document he found in the National Archives of Paris (Reference: Minutier Central des Notaires parisiens; Notaire Michel de Beauvais (XCVI-46); Date: 12 Jun 1646). It concerns the cutting of wood in the forest of Closse', a de'pendant of Bonne'table, one of the fiefs of the Comtesse of Soissons, Anne de MONTAFFIE', the widow of Charles de Bourbon, viceroy of New France at his death in 161 2. She had died in 1644. On second page: "Michel LARSONNEAU Sieur des Challongieres, one of the adjudicary associate s of these woods, absent at the redaction of this act, an d respresented by Denis COURTIN Sieur de la Trolandiere." L es Challongieres is at Challonges, a village annexed from t he actual commune of Seyssel on the Rhone, and from the district of St-Julien-dGe'ne'vois.

Pierre ARSENAULT arrived in Port Royal, Acadia from France in 1671. He helped establish a settlement there at Beaubassin (Footnote: Arsenault, HISTOIRE ET GENEALOGIE). Though most Louisiana families with the name descend from him, there was also a Michel ARSENAULT married to Marie-Anne ANDRÉ, a native of Cap de Madeleine near Quebec, living on the German Coast (St. John the Baptist Parish) at least by 1752.
It may be possible to confirm family relationships with Pierre by comparing test results with other
carriers of his Y-chromosome or his mother's mitochondrial DNA.
