Reminds me of the family where the custom was that the oldest male relative present at birth choose the babies' names. Twins were expected.
The father was called away on business, and the uncle stepped in. But he was known as a bit of a prankster...
...so the mother was relieved when, told she had a daughter, learned that the name was Denise.
And my son, she hopefully enquired of her brother?
Danephew, he replied.
