I Had a Little Nut Tree is a very old nursery rhyme. It was published first time in 1789. So it was maybe also used by your great-great-great-grandparents...? That's quite crazy, isn't it? Try to explain this to your kids.
I had a little nut tree,
Nothing would it bear
But a silver nutmeg
And a golden pear.
The King of Spain's daughter
Came to visit me
All for the sake
Of my little nut tree!
