Nickname HELP!!

[MMIP<3ZAX]

please anyone help! this is very difficult for us. i know its not right to ask strangers, but we are looking for a new tradition. in my line of my family tree, we have military rankings and double z's in our name. my 2nd littles tree has double e's and some form of their hometown in their name. my tree and my one little's tree names have become long and difficult. we want simplicity and meaning.
