You asked some great questions that I had not considered. Everything you mentioned would be wonderful information (confirmation, nearby graves because they might be related, death info, burial info, photos). I realize it is no easy task, so I'm very appreciative.
Could you also tell me the location of this cemetery (address) and what church it might be offiated with?
Yes, it should be Willa Augusta (she went by Aunt Bill).
Thank you so much for your help! I've searched online and can't find any of them.
