Adding credits for someone who went uncredited?

Hello,

I worked as a carer for a late woman who worked as an assistant editor for the BBC, I’ve been working with her family to get her credited for some the work she carried out but was not credited for. I have been in contact with the BBC written archives and they have a list of shows she has worked on but they will not digitize it, so I have no way of using it as evidence. They did send me a list but it’s not accessible anywhere else. Is there any way I can get still use the list or the emails as evidence?
