He would be my Grandmother's Uncle.
His brother's would include VICTOR BORRERO Y CRUZ and FRUCTUOSO BORRERO Y CRUZ and MODESTO BORRERO Y CRUZ.
He had a son JUAN RAMON ROSARIO from a first wife who died before 1920
From the second wife had Two or Three daughters... I do not know their names.
There is some sort of connection to a CORNELIA ROSARIO (she is his point of contact in his WWI Draft Registration card) of MACANA, Penuelas.
Any information would be greatly appreciated
