It was the first time I had come across a wrongly (originally) published Registration. I checked an "Ada Pratt" for Dec. 1919, Free BMD images. Wrong page! Then checked "Laura Pratt" and found Liilian. Everything ties up nicely on the Probate Index as Bessie D. Bowes (now we know her as Spiller) is William and Lillian's first (and only?) child. Born Hinckley. Many thanks for your help.
