Our little boy is named Tobias John and is called Toby. I knew that if we had a boy I would want for his middle name to be John as it's my Dad's name. The first name was more difficult.
We have an unusual surname so we wanted for the baby's first name to be recognisable and easy to spell. Traditional but not very popular. We also wanted to give him a long name and use a shortened version so that he had some flexibility. My name is Katherine but I was called Kathy as a child. I switched to Katherine when I left school and always appreciated that I had that flexibility in my name.
We looked through lots of name books and were trying to decide between Thomas and Tobias when someone gave me the book Miss Garnett's Angel about Tobias and the angel. I then remembered the Verrochio painting at the National Gallery of Tobias and the Angel and the name shot to the top of the list. We still waited to see our baby before we made a definite decision but he was a Toby as soon as we saw him.
