Molina did not stop from being interested for the fate of his family. He corresponded with them until 1795. He knew of the death of his mother, his brother, and his nephew Agustín Molina, the only male in the family and heir to his grandparents' fortune. The ungrateful nephew, who never had a deference for his uncle who lived in exile beyond the seas, married Doña Manuela Vergara, with whom he was neither happy nor succeeded. Upon his death, which occurred suddenly in the houses of the Huaraculén hacienda in February 1815, his property was passed on to his uncle, who was the sole heir.
