I'm very pleased that you've finally found out about Abel !
Here's what I have regarding his parents:
Pierre aka Pierriche Allain (s/o François and Catherine Huard) m.(1) July 8, 1833 Paspébiac Modeste Duguay (d/o Julien and Modeste Duguay) b. Jan. 1, 1812 and buried in Port-Daniel on Sept. 21, 1897, m.(2) Jan. 25, 1823 Geneviève Anglehart (d/o Jean-Baptiste and Anne Chapados).
Pierre and Modeste had at least 5 children:
Adeline (Marie-Adeline) b. Oct. 16, 1836 Paspébiac m. Sept. 30, 1873 Charles Blais
Pierre b. June 3, 1841 and buried on Dec. 1, 1892 in Paspébiac m. Jan. 7, 1864 Elizabeth Duguay
Joseph b. Nov. 13, 1843 m. Jan. 10, 1870 in Paspébiac Marie-Marguerite Hardy
Théophite m. Jan. 20, 1862 in Paspébiac Isaac Dunys (Denys)
Pierre and Modeste are my 4th grand-parents by their daughter Théophite.
Your John A. Allain should be Jean-Abel Allain which was born March 1, 1873 in Paspébiac.
There are still a lot of Allain living in Port-Daniel, Paspébiac, Anse-aux-Gascons, Newport (Bay Chaleur area in Bonaventure County)
