I see what you mean. Checking that marriage in 1855, I see that the groom was called Jean-Baptiste Riel (or Réel), not Arrhur Rouleau, so this is actually not the right couple. I apologize for my incorrect statement.
I cannot find any record of the marriage of Arthur Rouleau and Philomène Leroux. I will contact the system administrator, as I now strongly suspect that the children indicated for this couple (Adélard, Joseph and Mélina Rouleau) may not have been attributed correctly.
