We are thinking [name_m]Will[/name_m], [name_m]Ben[/name_m], [name_m]Jasper[/name_m], [name_u]Theo[/name_u] or [name_m]Leo[/name_m]
Last name is [name_m]Crandall[/name_m] which is tough daughters name is [name_f]Ava[/name_f]. I think I am partial to [name_m]Jasper[/name_m] and [name_u]Theo[/name_u] …would appreciate any input 
[name_m]Jasper[/name_m], [name_u]Theo[/name_u], and [name_m]Leo[/name_m] are all fantastic names. I’m partial to [name_m]Leo[/name_m] with [name_f]Ava[/name_f], just because they are so symmetrical! If you want to use [name_m]Ben[/name_m] or [name_m]Will[/name_m], however, I’d suggest putting [name_m]Benjamin[/name_m] or [name_m]William[/name_m] on the birth certificate.
I like [name_u]Theo[/name_u]!
I like [name_m]Benjamin[/name_m]!
I like [name_m]Leo[/name_m] -[name_m]Crandall[/name_m] it pairs nicely with [name_f]Ava[/name_f]-[name_m]Crandall[/name_m]
[name_m]Ben[/name_m], [name_m]Will[/name_m], and [name_u]Theo[/name_u] sound AND look incomplete
[name_m]Jaspar[/name_m] [name_m]Crandall[/name_m] is amazing, but next to [name_f]Ava[/name_f]- his name would potentially over power his sisters name. This is why I chose [name_m]Leo[/name_m] as a suggestion. [name_m]Leo[/name_m] is dominant on his own, a stand alone name, just like [name_f]Ava[/name_f], and both names are rich with history. But it is ultimately your choice and what you feel comfortable with and [name_u]LOVE[/name_u]. [name_f]My[/name_f] best of wishes and Congrats! 
I like [name_m]Jasper[/name_m]. [name_m]How[/name_m] about [name_m]Jasper[/name_m] [name_u]Seth[/name_u] [name_m]Crandall[/name_m] or [name_m]Jasper[/name_m] [name_m]Thomas[/name_m] [name_m]Crandall[/name_m]?
You’ve got a great start – early congratulations!
I love [name_m]Leo[/name_m]. It would be my first choice. [name_m]Jasper[/name_m] is a close second.
Other possibilities:
[name_f]Ava[/name_f] and [name_m]Levi[/name_m]
[name_f]Ava[/name_f] and [name_m]Ezra[/name_m] (powerful!)
[name_f]Ava[/name_f] and [name_m]Henry[/name_m]
[name_f]Ava[/name_f] and [name_m]Fritz[/name_m] (Very [name_m]German[/name_m], nice!)
[name_f]Ava[/name_f] and [name_m]Arthur[/name_m] (if you want to stick with the A’s)
[name_f]Ava[/name_f] and [name_u]Max[/name_u] (I think [name_u]Max[/name_u] is strong enough to stand alone.)
[name_f]Ava[/name_f] and [name_m]Isaac[/name_m] ([name_m]Both[/name_m] are popular, but I love the vowel sounds.)
Good luck! Be sure to post your little boy’s name in announcements after he arrives.
I really like [name_f]Ava[/name_f] and [name_m]Jasper[/name_m] together and [name_m]Jasper[/name_m] [name_m]Crandall[/name_m] sounds really nice.
This is being very picky, but it may be a concern for you. I dunno. When I say [name_m]Leo[/name_m] or [name_u]Theo[/name_u] with your last name I actually have difficulty because of the “o” and “l” endings. It may just be the way that I speak. However, because of my little issue my favorite is [name_m]Jasper[/name_m]. I think [name_f]Ava[/name_f] and [name_m]Jasper[/name_m] make a cute and spunky name pair! Good luck!
Thank you for the advice and input!! Very helpful You all said what I was thinking…I guess i needed people outside of family to weigh in. [name_f]My[/name_f] two favorites are [name_m]Leo[/name_m] and [name_m]Jasper[/name_m] …not so much for my husband …but he has time to mull it over. I agree our last name is a tough one probably why this has been so hard. that and I really wanted a dynamic name that paired well with [name_f]Ava[/name_f]
I love the name [name_u]Theo[/name_u], and [name_m]Jasper[/name_m] is also a great one
I don’t think [name_u]Theo[/name_u] looks incomplete in the way [name_m]Will[/name_m] or [name_m]Ben[/name_m] does. [name_u]Theo[/name_u] is a name all on its own
[name_u]Theo[/name_u] and [name_f]Ava[/name_f] [name_m]Crandall[/name_m] is just adorable
Ohhh!
[name_m]Jasper[/name_m] [name_m]Crandall[/name_m] is nice.
And I think it pairs well with [name_f]Ava[/name_f]!
[name_u]Theo[/name_u] is a better choice than [name_m]Leo[/name_m] for me, but both work.
