Thoughts on Adhira?

Is the "dh" hard to pronounce? Would one be able to pronounce it intuitively?

Also, some websites say that Adhira means "Restless" in Sanskrit, and some say it means "Lightning". Should I ignore the fact that the name means 'restless'?

I've already dropped the name "Leah" because many name websites said it means "Weary"

Really love the sound of the names Leah and Adhira. Leah is more playful while Adhira sounds strong.
What do you guys think?

TIA
