Mrs. Gardner and her photos

Here's Mrs. Gardner who brings Miles to her house to get rid of the ghost of her murdered grandson. I've included a wide shot of the street she lives on. Inside the hosue, you'll see some photos on the wall, the main one resembles Mr. Eko as a kid(I'm not saying it's him, but there is a resemblance). Something about this woman and her family seems important or at least to tie in to something or someone we already know.
