I've changed the names and location, but here is part of a birth announcement I read recently: "...paternal grandparents are Jim and Lori Smith of Dingdongtown. Paternal great-grandparents are Susan Smith, Plowville, and the late Bubba Smith and Ken and Susan Markle of Allentown."
The question is: are Ken and Susan alive or dead?
Of course people living today know what the paper intended. What would someone in fifty years think?
