With this talk of syllables, I guess it's good to mention that whether there are a lot or a few syllables, it makes a difference in the feel of it. Short sounds feel very masculine and conservative, like John Paul Smith. Lots of syllables are more unusual and can seem either old fashioned or flashy... eg Esteban Theodore Rodriguez.
I like longer, more complicated names, they're familiar to me. My old name: xxx xxx xx-xx. New name: xxx xxx/x xx-xx. My dad's name: xxx xxx xx-xxx. A cousin's name: x xx xx xx-xxx-xx. (Latino relatives, multiple hyphens and several middle names are common) So, it fits my family history. You might want to figure out the pattern of your family names and try to copy the rhythm.
