My two are Niamh Margaret Rose and Isobel Kathryn Eve.
Niamh's middle names are after my Nan and my H's Nan who were both called Margaret and are no longer with us. Rose is my other Nan's middle name - I wanted to include her but her first name is Winifred and I didn't like that! TBH she hates being Winnie too so was really pleased we used Rose.
Isobel's middle names are Kathryn after my best friend who has just been an absolute star especially since I had the girls. Other friends have fallen by the wayside since I became a Mum but she has been a real rock when i have struggled. She is not a Mum herself but she gives me really practical help and if she doesn't agree with all aspects of my parenting, she keeps it to herself! Eve is after H's other Nan who was called Evelyn but known as Eve. H really liked Eve but obviously we couldn't have Eve and Niamh!
