This record gives valuable birth and baptism information I am not used to seeing in a marriage record.
Married 6 Nov 1837, Matriz (de São Jorge) da Vila das Velas.
Groom is Antonio José de Sequeira, son of Manuel Vieira and Rosa Maria Sequeira, both deceased; native of this matriz born on 8 May 1804 and baptized on 13 of the same month.
Bride is Barbara Florinda, daughter of José Inácio da Silveira and Maria Barbara, she is deceased; native of NS das Neves, lugar de Norte Grande born on 6 Oct 1807 and baptized on 12? of the same month.
I believe the groom's parents are both deceased because the end of "defuntos" trails down like an "s" while for the bride's mother the end of the word trails right like an "a" (defuntos vs. defunta)
I hope this helps.
