We're naming DD Sophia Jordana or Sophia Giordana (DH said the spelling of the middle name is really up to me) and our last name is a VERY common Jewish last name.
Her middle name is after my grandfather, whose name was George. I"m not sure how I feel about the Giordana spelling (and DH doesn't like Geordana), but while I like the J spelling a lot, I'm also not sure how I feel about naming her with a J since my grandfather's name started with a G. Am I not really honoring him since it's the same sound, and not the same letter? We're planning to use the same letter as my grandfather for her hebrew name either way.
What are your thoughts and WWYD?
Re: Naming after relatives- WWYD
You've probably nixed this already, but what about the name Georgette?
Honestly, if you want to abide by the tradition of using the first letter, I would pick a different name altogether than Jordana or Giordana. If you don't really care too much about following tradition, but like the name enough, I'd just go with Jordana.
I am Jewish and based on discussions with my Rabbi, there are many Traditions about how to name a child after someone. It's a tradtion, not a law. Most name after somoene who is deceased, but apprantly the Sephardim name after an older relative to honor tham. many Ashkanizi older relatives may find that offensive, so he advised that if we wanted to go that route to check with the living relative first.
As far as the name, one popular/common tradition is the first letter, some use the full name, some only use the hebrew name. My mom did a sound alike (as only my mom could pull offf) that my great grandfather Huna, sounded like Linda as she didn't like any H names. My hebrew name is the feminie form, elchana. I would recommend talking to your Rabbi if you have one you are close to. I personally think that you have to do what you and DH are comfortable with and if you are both comfortable with the same sound-go for it! In my opinion if you have in your heart you are honoring the person by naming after them, that's all that matters.
