Today I wanted to explain what is meant by the term 'sib-sets'. People who like baby names often talk about sib-sets to describe the names given to brothers and sisters in one family. A sib-set displays the parents' naming style much better than just a single name. Most parents will go with a certain type of name for all their children. There is more to think about when naming second, third etc children because they have to sound 'right' with the other names already picked.
So, for example, if you were to choose the name Hudson for your first child, it would seem rather mismatched to name a second son Benedict. Hudson is trendy and modern, Benedict is old-fashioned and distinguished. It's not always as obvious as this but it's something to bear in mind.
You also might want to think about going for similar popularity. You may not want to name a daughter Aurora and then your son, Stephen. Perhaps Soren would make a better choice?
Another consideration is number of syllables and sounds within names. This is less important, although it can be nice to have similar lengths to names. An example of this working well would be: Annabelle, Violet and Oliver. However, I think Isla, Amelia and Nate also sound lovely together because of similar sounds and similar styles. I guess you may want to avoid any really obvious differences, such as Sebastian, Isabella and Jay.
I find sib-sets fascinating and I love trying to work out connections between siblings' names. I love it when parents add in hidden connections, such as similar meanings in all their names, or the use of a theme (word names, nature names, virtue names - perhaps this is more appropriate for middle names?).
There is a lot to think about when naming subsequent children but, then again, the very most important factor is always whether you, as parents, like the names you have chosen. I don't agree at all with forcing a theme on all your names (eg - same letter for all names) or discarding a long-loved name because 'it wouldn't go'. Where would be the fun in that?
