I’m still in the process of TTC 
But like all name lovers I’m creating my name lists.
In my mind, since the surname will begin with an A, then the first name shouldn’t end with an A since they will flow together. Last name sounds is 3 syllables starts with Ar…
Anything like [name]Claudia[/name], [name]Cara[/name], [name]Sarah[/name]… [name]Will[/name] just flow badly.
Am I right?
I would tend to agree…I think that a name ending in A would flow directly into your surname.
I would also avoid names that share the -ar sound ([name]Claire[/name], for instance0; they would be a bit too rhymey with you last name.
Thanks. It limits a lot of girl names since so many of my favorites end with A. 
I usually agree with this rule, but I think A sounds are more forgivable than S sounds, for example. I wouldn’t do [name]Alice[/name] [name]Smith[/name], but something like [name]Clara[/name] [name]Anderson[/name] is okay, especially since A can change its sound. [name]Claudia[/name] doesn’t end in a short A like in “cat,” but your last name might; the two separate sounds break it up a bit.
I would run any favorite combinations in a poll and see what people say. You might be surprised!
I think it depends.
[name]Clara[/name] Arasol sounds terrible
[name]Priscilla[/name] Arrogant sounds okay
[name]Geneva[/name] [name]Arlington[/name] sounds amazing!
I agree with r_j that a lot depends on whether your last name begins with a long or short/soft or hard A sound.
I might agree with your rule in more situations if your ln was something like Adescue (uh-des-Q). Because that uhh sound is how most ending -a names sound. Dorah Adescue…not so much
But since you said it’s Ar-- I’d imagine it’s more likely it’s pronounced as AIR or ARR. In that case I’d be more worried about R ending names. Oscar Archane is a bit much.
Honestly, I think it depends. I’d advise you go on a case-by-case basis. I don’t see the point in disregarding [name]EVERY[/name] name that ends in A because 1) not all of them will sound bad with your surname, and 2) you may miss out on something you really love.
I don’t feel like any ‘rules’ are worth missing out on a name you truly love. It drives me bonkers to see people complain about not being able to find a name they love and then “but we have 25 rules to follow”, well no kidding you can’t find anything 
I think if you love a name, and the flow is not 100% perfect, you should use it anyway.
@kala_way’s examples of which -a names work with an Ar- name are great!
I think something that ends with an “ah” sound, like [name]Clara[/name], [name]Sarah[/name] and [name]Claudia[/name], sounds differently enough from a last name that starts with an “ar” sound.
For example [name]Claudia[/name] [name]Arlington[/name] sounds fine. “[name]Ah[/name]” and “ar” are too different sounds.
Thanks so much for this great feedback. I will collect all my favorite names and see how they work with my bf’s last name. It actually does begin with the ARR sound not [name]AIR[/name] but I won’t be limited by any rules
