"A registrada contraiu casamento 'in articulo mortis' no dia 29 de Fevereiro de 1936 com João de Sousa Delgado, natural de freguesia de São Pedro, concelho de Vila Franco do Campo, cujo casamento foi ratificado no dia 20 de Maio de 1936.
I believe this means she contracted marriage with Joao de Sousa Delgado on the brink of his death on 29 Feb 1936 which was ratified on 20 May 1936. "in articulo mortis" is a latin phrase that means on the brink of death, In the case of marriage, it gives urgency to bypass the normal banns and secure the rights of the spouse.
