Nuala

My name is Nuala- my given baptismal name. I have never identified myself as a diminutive of Fionnuala even though linguistically this is true. I was deeply upset to hear my husband tell somebody who was admiring my name that I was really called Fionnuala. He also referred to me as Fionnuala when giving a speech at work. Any other Nuala's out there feel like this? Have to admit I felt it was like identity theft. Didn't help that he had a friend called Fionnuala but he didn't call her Nuala.
