The line runs back through the Obey family of Penobscot County to Thomas Aubut and Obeline Dube, married on 29 February 1848 at Saint-Jean-Baptiste parish, L'Isle-Verte, in Quebec. Their son is recorded both as John William Obey and as William Aubut, 1859 to 1923, born at Holden, Maine, and his son was John Joseph Obey, born at Bradley, Maine on 28 September 1887 and died at Bangor on 22 December 1983. John Joseph married Mary Elizabeth Call at Bangor on 29 June 1910. One further generation stands between them and the twentieth-century marriage that carried this line into the Sproul family, and she is left out of this public record because no death record has been found for her.
PRDH indexes every Catholic act in Quebec from 1621. A search by parental role pulled the four parents out of the 1848 act and confirmed them across three databases: the groom's parents were Pierre Frederic Aubut, 1783 to 1849, who died at L'Isle-Verte a year after the wedding, and Marie Felicite Morais or Morin, born 1785; the bride's parents were Magloire Dube, baptised 1796, and Esther Labourliere dite Laplante, 1805 to 1886. The act records Thomas 27 ans et Hombeline 20 ans, which fixes Obeline's birth at 10 March 1827. It was a double wedding: Thomas's sister Sara married Narcisse Delisle the same day, which is why Frederic appears twice in the record as father.
Francois Aubut was baptised on 27 May 1731 at Saint-Martin church in Les Biards, diocese of Avranches, Normandy, now part of Isigny-le-Buat in the Manche. He was a cod fisherman. He first crossed the Atlantic at sixteen with an uncle also named Francois to fish the Gulf of St. Lawrence, went home, crossed several more times, and then in 1755 sailed from Granville aboard le Prudent and landed at Gaspe, this time to stay. He married Marie-Louise Elisabeth Dupuis at Notre-Dame de Quebec cathedral on 18 July 1757 and died at Riviere-Ouelle on 9 November 1815. His family is documented in that one Normandy village back to 1598, and only three generations separate him from the Thomas who married in 1848.
Mathurin Dube was born about 1631 at La Chapelle-Themer, diocese of Lucon, in Bas-Poitou, today the Vendee. Seven unbroken generations run down from him to Obeline. His 1670 marriage contract survives, drawn by the notary Romain Becquet, and names his parents Jean, or Yvon, Dube and Renee Suzanne. That is a primary document, not a compilation.
Two of the roughly 770 Filles du Roi, the women the French crown sent to New France between 1663 and 1673, are ancestors. Marie Campion married Mathurin Dube in 1670, and Anne Gasnier, the woman who personally placed the Filles du Roi, was present at the signing of the contract. Jeanne Savonnet, on the Aubut maternal side, arrived at Quebec on 31 July 1670 aboard La Nouvelle-France, married Jean Soucy dit Lavigne of the Carignan-Salieres regiment, and outlived three husbands.
How they reached Maine: L'Isle-Verte, then Saint-Basile in Madawaska, New Brunswick, where a son was born in 1853, then Holden, Maine by 1859. That is the Temiscouata portage route, and the Madawaska stop is documented. The lumber motive is an inference, since no occupation record turned up, though Holden and Bradley are Penobscot lumber towns. The surname anglicised from Aubut to Obey along the way.
