I did look through the pictures I have and didn't come across an Anna K. Anderson. At least not a readable picture of one. There are a few stones that are unreadable due to age. I am attaching some pictures of the cemetery to give you an idea of what it looks like. It is an active cemetery with readable headstones. I can send you what pictures I have of the Andersons so you can see if they are any you need to add to your family tree. I hope this helps.
