T names are hard for me but I've tried my best!
Boys:
Thomas - Strong and classic.
Timothy - Classic but not too popular.
Tristan - An interseting name with a rich history behind it.
Tyler - I've loved this name ever since I saw the film Step-Up. It's maybe a bit on the trendy side but still very cool.
Ty - Can be used as a nickname for Tyler but is very cool on its own.
Taylor - Now often used for girls, this name still seems very masculine to me.
Tavish - A very cool and interesting Scottish name.
Tiernan - A strong and interesting Irish name.
Girls:
Theresa - A classic name that would age well.
Teresina - An elaborate, princessy name.
Teagan/Tegan - Very spunky and strong.
Tallulah - An intersting, spunky choice.
Tamsin - A very sophisticated and upper class sounding name.
Tamsene - Pronounced (tam-ZEEN) an exotic twist on Tamsin.
Tanyella - An elaborate and exotic name.
Thalia - A very pretty name that is unusual yet familiar.
