On the 19th of October 1857, I the undersigned priest with care of this parish, baptised Joseph, born yesterday to the lawful marriage of Joseph Roussel dit Davia, farmer, and Emily Hudon dite Beaulieu of this parish.

(Signed) Ch. Bégin (?)....
I couldn't make out the bit at the end which seemed to relate to the godparents, and I'm not 100% sure of the surnames, but hopefully this will help a bit.
