It is highly likely that Jose Florencio Manchego is from another branch of our Manchego root. The branch that I follow reaches Manuel Pedro Manchego's great-grandson before it begins to produce children in the 1862 timeframe.
I continue to attempt to identify all children of each Manchego to connect them to the whole family. I have seen Jose Florencio Manchego in my research, but have not yet made a connection to the branch I research.
Jose Florencio's father, Manuel, could be a son of Juan Christobal Manchego, or a descendent of his father, Juan Francisco, or a descendent of his father, Manuel Pedro.
