Looking at the register for St Jean-Baptiste in L'Original, I see a couple of baptisms for Alfreds, "born of parents unknown":

14 July 1867, Alfred, aged two and a half, along with a William Edouard:

B. 85 Alfred et William Edouard, illég. [illegitimate]
Le quartorze juillet mil huit cent soixante sept one été baptisés Alfred âgé de deux ans et demi et William Edouard âgé de trois mois nés de parents inconnus. Parrain Joseph Robillard et marrain Mary Ann Dunn, qui n’ont pas signer.
[The fourteenth July one thousand eight hundred and sixty seven were baptized Alfred, aged two and a half years, and William Edouard, aged three months, born of unknown parents. The godfather was Joseph Robillard and the godmother Mary Ann Dunn, who have not signed].

2 May 1871, Alfred, aged 3 months:
