A charge would have been for a certificate of the birth, not for registering it. Someone pointed out to me, many years back, when I started researching family, that "moveable ages" on censuses, etc, were often because people, especially in large families were not quite sure of their exact date of birth, or even age, and many never had a birth certificate because of cost, although quite legally and licitly born. I did once hear a very elderly man saying something to the effect of: "Well, I know that my dad was younger than our uncle Sammie, but Auntie Nora was older than him, and her Dad was younger than my grandad's youngest brother......" where families stretched over generations that could really foul up tracing exactly who was who, especially when they used only a few first names!
