I think you need to look carefully at your sourcing for a Baldo Flandrensis being husband of Adeline.
If Baldo existed, "Flandrensis" means "of Flanders", and is not a surname in the sense we would understand today. A Baldo of Flanders will not be the same as Piers de Ros who was probably born in Yorkshire, England. Reliable sourcing would be needed for a marriage to any Adeline Espec. Sources indicate that the Adeline with a WikiTree profile married Piers de Ros.
