His mother Hannah's bishop growing up was Marion G. Romney, who happened to be in town when Gawain was born and asked after Hannah. He was told she was in the hospital having just given birth to another Marion G! The Gawain is after Sir Gawain, because his father George liked the Prince Valiant comics featuring Sir Gawain.
Since he's on a mission in Europe, I hope he enjoys a birthday chat with his grandchildren and a taste of home today. We love you Papa!
