Onslow,
My cousin who has your same name along with his son use alternative versions of their name. My cousin uses his first and middle initials (Southern parents) and my cousins son just goes by their middle name, Ben. My dad and brother also had similarly scary names ( think of childhood rhyme .....,rastus johnson brown) my father just braved it out as did my grandfather but my brother goes by a nickname. One thing in their favor is that they were all handsome men so it counterbalanced it a bit. I find the same works for a contemporary British actor of the same name.

My name meaning "Gracious Warrior Queen" was number 5 in the 60's and 70's and held its own in the top 20 till this day.
