Everyone in my father's family had a nickname.
My Uncle Francis was called "Buzzy" or "Buzz" after someone commented that his legs looked like a buzzsaw when he ran while playing in high school football games. Uncle Clarence was called "Marco" after playing Marco Polo in a school play (who would want a handle like 'Clarence' anyway?) Aunt Dolly was always Aunt Dolly, I can't remember her real name. Aunt Tootsie's real name was Evelyn. The only kid who got to keep his given name was Walter, or "Wally". My father, Tommy, was called "Toto." Legend has it that this was a name for a doll or toy he was fond of. I thought he was nicknamed after the dog in 'The Wizard of Oz' but he was 12 yrs old when the movie came out.
I, Tom Jr., became "Tommy Tote", after "Toto" and later because of a picture of me on the beach in California with a tiny pail and a tiny shovel. I guess I carried a lot of stuff around in that pail.
Here's the odd one: My sister Maryann was called "little chicken" which she repeated as "chee-chee". That evolved into "Cheech" which morphed into "Cheechee Dookie, " "Dookie Doo," and "Dook." Everyone else called her Maryann, only my father called her "Cheech" or "Dook." Go figure.
I still have many nicknames: Bermshot, Big Block, Big Eye, Buck, Mr. Belvedere, The Gila Bender, Tommy the Beltfed, and just plain Tom.
