Where do I look for funding for PhD research in lost or rare silent films?

I am an MSc student at the University of Edinburgh, and I am currently applying for a PhD programme. I want to write my dissertation on silent film adaptations of Victorian Gothic novels, with a special emphasis on monster characters. I have already done a lot of research on this topic and have realized that I will have to travel to many international film archives to track down lost, rare, or partially lost silent films. This research may prove quite valuable from a historical/preservation perspective as I will be looking for forgotten or neglected films and bringing attention to their aesthetic and film historical value. I have run a basic Google search to look for funds for this work, but have found meager results. What sort societies, foundations, or other organizations may offer grants or scholarships for this type of research?
