Send a message to the person who requested a photo of the grave monument of Robert John McLachlan with the following comment:
My name is Juanita McLachlan. I'd always thought that I was the only person with my name, but now know that there are (or were) at least two others, with one of these being in South Africa and the other being the Juanita McLachlan on this headstone. There's another person in Indiana that shows up on a google search, but this is actually a case of identity theft.
