Lena-Andrea, prounounced, most acurately-LAYnuh awhnDRAYuh. To really prounounce it correctly you need to slightly roll the N in Lena-giving it a slight 'y' sound, kind a nyuh. With Andrea, roll the 'r'. My Great grandma, the gypsy, was key to naming me, I love my name, but there were times when it was heck to have. Most people assume it's just Lena, not hyphenated, and that Andrea is my middlename. Family and friends call me Lena, but I introduce my self Lena-Andrea lastname, I sign Lena-Andrea lastname, it's Lena-Andrea. Being I live in MN, most commonly I am called LEEna, but I also get lenna, lana, alana, and my personal favorites, Leah, Leanne, and Lian. I have been told that I misspelled my own name, by Gov't officials, that my mom must have misspelled it, the list goes on.
For a while, some friends decided to call me "Nandy"...that didn't fly. I have no problems correcting my name, but I shouldn't have to tell you everytime. My MIL is still prone to spell it wrong.
