I am looking for when Gabriel Rouleau died. A lot of people on Ancestry have 1821, including from one person that used his/her own citations. The citation for 1821 is absent on all of them. I'm thinking maybe he has a gravestone somewhere and that's what's used? Or maybe because the 1821 marriage record in Quebec City for Gabriel's son Francois indicates he had died?

The 1810 marriage record for Marguerite Rouleau has no indication of Gabriel having died.

Like Gabriel, I'm also having difficulty finding his son Joseph's marriage record to Josephte Guerard (1819), although a marriage contract passing before the notary Antoine-Archange Parent (https://applications.banq.qc.ca/apex/f?p=131:11:0::NO::P11_CLE:35746), and I imagine the actual contract still exists and is on microfilm somewhere. The repertoire of Antoine-Archange Parent's notarial acts is available on BANQ's website (http://bibnum2.banq.qc.ca/bna/notaires/pdf/03Q/CN301/03Q_CN301S212/01.R%E9pertoire%20chronologique/1819-1820/03Q_CN301S212R_0025_P024.pdf), but it doesn't seem to have the corresponding notarial act available.

The 1821 marriage record for Francois Rouleau indicates that Gabriel had died, and (incorrectly) that Therese Cote had died (unless I'm misreading it).

Therese Cote died at St. Roch Parish, Quebec City in 1832. She had her funeral at St. Pierre, Ile d'Orleans, and it's stated that she was widow of Gabriel Rouleau.

I have not yet gone through birth records to see if Gabriel was ever named godfather to any of his grandchildren in order to narrow it down more.

Anyone have any ideas?

He died between 02/1811 and 02/1819.  There's no death date on PRDH while they give Thérèse's death date.
