this might be an impossible ask
looking for a marriage [possibly Dublin] of Hannah Tucker born c1824 Ireland,
her husband could be under several variations of his name, MARIANO THEODORE CASTRO DE GISTAU, sometimes its just Castro or De Castro, he was a teacher of languages and a musician , by 1842 they were in London, England then in Scotland, then back to England, I cannot find a marriage in England and Historic papers say he spent time in Ireland.
