I have this belive that Rafael Hernández-Marín family is conected to the Yumet family. The reason is I know there are Yumet-Hernández and Yumet-Marín. Aguadilla was not a big town then or now so to have those two last names makes it possible that they are related.
Rafael had a sister named Victoria Hernández-Marín she could have married one of the Yumet also Rafael had a brother named Jesus Hernández-Marín. They are to close not to be woven into the Yumet tree some how. I will keep my eyes open to see if can make the conection. Buena suerte a todos.
