My father is the youngest child of an old couple. His father was the 14th of those 15 children mentioned above (and in the end the only child to pass on Medder, so every Medder in NZ is directly related to me!). My oldest aunty gave me this information, as she researched her and my uncle's (dad's eldest brother) family trees. It's entirely possible it was done from one of my grandfather's siblings' memories.
