We do have a surname Perkins, I had thought that right side letter was a G since it is larger than the P, but maybe not. I need to start hunting for some Phoebes, Pauls, Peters or Phyllis' etc. in the family that could explain the initials. This should be a family member, but I expect it's going to be a sister, aunt or something like that, since it doesn't seem to match anyone in my direct line.
