Do you have a middle name?

[Trevor]

My middle initial is T ~ for my family here it stands for Thomas, after my Dad and to my fellow Trekkers / Trekkies, it stands for 'Tiberius'. 

Someone was once physically up in my face and asking what the T stood for: I said "In your case, it stands for 'Trouble'." 

[Doggett]

Mines Robert. 

[The Burgomaster]

Louis

[3mnkids]

Lynn

[JJ80]

In my case John.

[Jack]

Thomas.  I don't think the Tiberius thing would work too well in my case - a Roman middle name would kind of clash with my Polish last name.

[Leah]

again with Thomas, after my dad.

hi
I am the original "Beast" my middle name is Vincent.

[The Gravekeeper]

Elizabeth, after my great-aunt. Heck, my first and middle names are both in honour of family members. I guess it's better than my sister, who was named after a song and a holiday.

Only real significance I can think of is all the men in my family have the middle inital A.
