Finally I did check the church records for the marriage record of a Pascal Leclerc (son of Clément Leclerc and Lucie (luce) Fournier) to Julie (?)Clais (as per a database I was using) d.o. Edouard (?)Clais and Angélique Pouliot) 4 Apr 1855, Notre-Dame de Québec.
There is doubt that this is the right Pascal and Julie.
The priest wrote what appeas to be CLAY as surname of the bride.Fortunately, she did sign the record as well as Pascal and she signed Cenais.The C or S before an E sound the same so we easily get Senais which is a synonym of Senez.
For further proof, Julie's father was married under the surname of Senay (same as Senais essentially).
Cannot remember if you were looking for the ancestry of Pascal or Julie.I do have some ancestry of Pascal if this is what you are looking for.
Still no luck trying to link Julie Genest to Pascal.However, that person could be Julie Senais/senez but why a date of death of 1886?If this is the real date of death, Pascal would have had to be divorced from Julie. But divorces did not exist in those days.Marriage annulation maybe which would have allowed him to remarry.
On the basis of Pascal 2nd marriage date to Nathalie and Alphonse's marriage date, these two events occurred 10years apart.One hypothesis is that Alphonse was born out of wedlock prior to 1871.
