The Sound of the Name
The general “sound” and rhythm of the name is a very important factor in choosing a name.  In general, the number of syllables in the first name should not match the number of syllables in the last name.
Your child will hear it over and over again and you will have to say it over and over again.   Ask yourself if the name sounds pleasant when you say it aloud? Combine it with your surname and with middle names you are considering.  If you have other children, how does the name you have in mind go together with their names?  How your baby's name sounds when it's said aloud is one of the most important things to think about. Does it go well with your surname? Is it melodious or Harsh? Often, you will find that longer first names go better with shorter surnames, and vice versa.  Balance the first name with the surname. If the surname is common, such as Jones, a slightly unusual, longer first name is the best idea.  A long, unusual surname can be balanced with a more familiar first name.  Alliteration can be used to good effect such as Jeramiah Johnson or Daniel Defoe, Benny Blackmore.  These combinations are easier to remember too. You will say the name thousands of times. You will say it lovingly and in anger. You will whisper it when the child is asleep and yell it when dinner is ready. See how it sounds!
 

Vowels & Consonants
Try not to combine a first name that ends in a vowel with a surname that starts with a vowel. The names tend to run together e.g. Anna Anders, Jerry Yonker or Diedre Eaton
Don’t use first names that rhyme with your surname such as Peter Fleeter.  Avoid using puns, they will be funny for everyone except the child.  A name like "Holly Wood" or “Scott Land” ,“Ann Teak” or “Candy Barr” would be disastrous. Your child will be stuck with a silly name for the rest of their life.  Some people advise going out to the back door and shout the name a few times just to make sure it sounds right. Hopefully the neighbors will either approve or possibly enquire if you are feeling well or not!
