First off, I’m not planning on having any more babies, this is just for fun!
I noticed that all of my children’s middles are three syllables and contain the letter L somewhere. The names in question are Matilda, Valentine, Helena and Gabriel.
It got me thinking: what else could fit the pattern?
These are already on my middles list…
Apolline
Cicely
Clementine
Ferelith
Leontine
Madelief
Marceline
Marsaili
Ottoline
Pipaluk
What else would fit?
