What about...

I like it - one of my besties is Greta which you could shorten Gretchen to, she also gets Gret for short

Thanks for the feedback.

I like the name. I can see it for a child or an old lady. Just not sure about inbetween. DH and I both decided against it initially, but I keep coming back to it.

As for shortening, we're not big on shortening names (DD1 is Amelia and we don't shorten that). But Greta is a possibility (thanks Nai).
