Amy is a classic!
However is you pair it with any name that was trendy/popular during the 70s and 80s it will sound dated.
Amy Jessica, Amy Rebecca, Amy Michelle
These freshen it up:
Amy Olivia, Amy Piper, Amy Scarlett, Amy Violet, Amy Reese, Amy Lydia, Amy Adelaide
I think Amy does fit with your girls names.
Thanks for all the input!! It has been an interesting discussion :) Alas hubby pulled it off the table (and pretty quickly after I mentioned it)... my SIL is named Amisue....and goes by "Ami", and well, sadly let's just say, she is not his favorite person. I don't see the big deal; as her name is really not Amy, but then again I am much more forgiving with associations when it comes to names I like then he is... SO... looks like we are back to Anna Caroline........
I would say...it's not dated or classic. Sarah is a little more classic. Maybe this is more like Rachel? It has that 80's , 90's vibe, but it is also an charmingly vintage name with a lot of great history. A little Amy coming up today would share her name with a lot of the mom set, but it's like meeting a late 20's/early 30's Joan or Lorraine...if it's a good solid name I think it's OK. But I forgive the dated thing pretty easily. I even see the naturey charm of Heather, Amber, Dawn & Robin...
Friends named a baby (born in 2012) Amy. My first reaction was "wow... how dated!" but like many opinionated topics, seeing little Amy and knowing her family, it seems to work really well. A name being dated is all about the context I think. :)
I think Amy works with your sibset, but I see your DH does not like it so it's a moot point. I wanted to weigh in though.
It's classic but also very tired. I think it's time to give Amy a rest but I do recognize that it's a quality name.
I find it be both classic AND dated. By that I mean it is classic in the sense that it's been around for a long time but it still feels dated in the because it feels like an 80's name. Keyword being "feels", because I know it is in fact not an 80's name. (Just looked it up on the SSA site and turns out it is actually a 70's name as it peaked then and was in the top 10, almost the top 5, for over a decade). It is a sweet name, but its just lacking something.
