My husband and I both like this and are considering it for our daughter. We’ve received strong opinions from friends and family - both positive and negative. While I believe it may be a surname in Australia, in some senses I guess it’s not really a “real” name. We just think it’s pretty and unique sounding. What are your thoughts? Is it too weird? Is the lack of origin/history and meaning a problem? Could people grow to love it? 
Thanks!
I think you need to go into it very aware that she will likely be spelling/explaining her name every. time. she introduces herself. For the rest of her life. And deflecting the repeat-back of a not-quite-sure-I-heard-you-right. This conversation will happen umpteen times:
[name]Hi[/name], I’m Rylah, nice to meet you.
[name]Lila[/name]?
Rylah.
[name]Kyla[/name]?
No, Rylah. R-y-l-a-h.
Oh, that’s pretty, is it from somewhere?
No, just made up.
[name]Hi[/name] there! Yes, I appreciate that will likely happen a lot and it’s definitely something I’m concerned about. Thanks for your feedback!
I don’t think Rylah is weird, since it has a sound similar to [name]Riley[/name], [name]Lila[/name], etc. However I do think it sounds invented. If that doesn’t bother you than go for it. The most important thing is that you love your daughter’s name and are happy with it in the long run. But if you’re on the fence, then I might choose something with a similar sound or feel but that also has a little history.
[name]Rilla[/name]: can stand alone or be a nn for [name]Marilla[/name] (maybe even [name]Aurelia[/name]?)
[name]Raina[/name]: I love the meaning, “queen”
[name]Lila[/name]: Getting to be quite popular but a really lovely name
[name]Calla[/name]: Another pretty flower name, and not nearly as popular as [name]Lila[/name]
[name]Isla[/name]: Also moving up the charts…
[name]Milla[/name]: [name]Love[/name] as a nn for [name]Camilla[/name]
[name]Roma[/name]: Interesting twist on the place-name trend (nn [name]Romy[/name]?)
[name]Rose[/name]: Might be a little old-fashioned for your tastes…[name]Rosa[/name] adds an extra kick 
Good luck!
Thanks olivegreen, these are great suggestions!
I don’t believe Rylah is too weird. My nephew has a very uncommon name and sounds “invented”, but he gets tons of compliments! We used to think he was the only kid named that until I met an adult with his name and heard of two other children named this but live nowhere near us. Rylah won’t be common of course but i doubt she’ll be the only one in the world with this name
Also, I have a name that’s not common and sounds identical to others that are, but the only time I get the person asking again to make sure they heard correctly is over the phone (then I spell it for them), in person however, they get my name right the first time they hear it.
Thanks!
It’s new but I don’t think it qualifies as weird.
I actually love the name Rylah! I love names with y’s in them…
Plus, I was in a line, squished in with a bunch of other people, and I just happened to look over at someone’s phone… They were texting someone named Rylah!
So there is at least one already in the world.
However, Rylah is the last name of [name]David[/name] Rylah, who does Bodies Made Easy.
It may disappear before Rylah would be at a teasing age, but I just thought I should point it out.
Rylah is not ‘weird’, because it fits in perfectly with current trends. Names like [name]Riley[/name], [name]Lilah[/name], [name]Ryan[/name], and [name]Kayla[/name] are part of a huge trend of names that are made up or taken from surnames/boy’s names just because they ‘sound nice’. I really wouldn’t suggest you name your daughter Rylah, because it’ll eventually sound dated and tryndeigh and not serve her well as an adult. Plus, I personally think it has an unattractive look and sound. Here are similar, legitimate names:
[name]Lyra[/name]
[name]Rilla[/name]
[name]Lila[/name]
[name]Aurelia[/name]
[name]Rhiannon[/name]
[name]Isla[/name]
[name]Aurelie[/name]
[name]Laura[/name]
[name]Laurel[/name]
I agree that Rylah is definitely not weird but is a little trendy
I love the previous suggestion of [name]Rilla[/name] as an alternative - it can also be a nn for [name]Marilla[/name]
But Rylah most strongly reminds me of [name]Isla[/name] (which is getting quite popular) and [name]Ryland[/name], a name listed on nameberry as a boys name but the only [name]Ryland[/name] I ever knew was a girl
