History denied does not make it so.
jimelena, These refugees did originate from this area. It's an act of historical ethnic cleansing to deny it. While you want to explore whether or not these people were residents of Palestine, At the same time, keep in mind - Who denies it and what is the benefit?
There are many historical documents that detail their history, but maybe you will believe your own eyes with pictures. Viewing these pictures, it's striking to me all of the history and culture that has been lost, and it's such a shame because it was exotically beautiful.

Some of the same are here, without bibliographic information but there are some pictures viewable here, that aren't large enough to see on the gov site without buying them.
