Names with the same letter??

Jenna
What are your thoughts on naming kids all with the same letter or meaning almost all of your kids with the same letter and one kid with a different letter? My oldest boy we named Seth Michael then my daughter we named after my grandma Sophie a lot of people thought we did it to make names both s which bugged me then my third we named Emily and our fourth sailor and now we're expecting our fifth not sure what we're going to name them just curious what people thought
