Wanting a middle name to match a girls name [name_f]Saylah[/name_f] (pronounced [name_u]Sailor[/name_u]), either spelt [name_f]Saylah[/name_f] or [name_u]Saylor[/name_u].
If you won’t be using [name_u]Sailor[/name_u], I would say go with [name_u]Saylor[/name_u].
[name_u]Saylor[/name_u] [name_f]Marie[/name_f]
[name_u]Saylor[/name_u] [name_f]Jane[/name_f]
[name_u]Saylor[/name_u] [name_f]Cosette[/name_f]
[name_u]Saylor[/name_u] [name_f]Louise[/name_f]

[name_u]Saylor[/name_u] [name_f]Honora[/name_f]
I’m not sure what kind of names you wanted to “match” [name_u]Saylor[/name_u] with… I think [name_u]Saylor[/name_u] would work better with a more classic name.
If you’re going to pronounce it [name_u]Sailor[/name_u], you might as well go with a spelling that reflects that. [name_f]Saylah[/name_f] sounds like [name_f]Kayla[/name_f], not [name_u]Saylor[/name_u].
I also think a classic would work well with this.
[name_u]Saylor[/name_u] [name_f]Grace[/name_f]

I [name_u]LOVE[/name_u] the name [name_f]Saylah[/name_f]! Like I’ve seriously been in love with it for several years now. However, if you want to pronounce it as “sailor”, then go with [name_u]Saylor[/name_u]. 
What other names do you like? So we can get a sense of your naming style.
I pronounce both [name_u]Saylor[/name_u] and [name_f]Saylah[/name_f] differently than I do [name_u]Sailor[/name_u], but picking between the two, I’d overwhelmingly choose [name_u]Saylor[/name_u]. Cute name!
[name_u]Saylor[/name_u] [name_f]Hazel[/name_f], maybe?
[name_u]Saylor[/name_u] [name_f]Evangeline[/name_f], [name_u]Saylor[/name_u] [name_f]Ruth[/name_f], [name_u]Saylor[/name_u] [name_f]Madeline[/name_f], [name_u]Saylor[/name_u] [name_f]Catherine[/name_f].

I think one syllable namers make saylor sound a litle lik an adjective -like [name_f]Bonnie[/name_f].
I like 2 syllables with stress on 2nd syllable.
Totally curious… how do you pronounce [name_u]Saylor[/name_u] and [name_u]Sailor[/name_u] differently?
Nobody’s going to pronounce [name_f]Saylah[/name_f] as [name_u]Sailor[/name_u]… if that’s the pronunciation you’re going for, you’re going to have to use [name_u]Saylor[/name_u].
I think you should go with a one-syllable middle name… [name_u]Saylor[/name_u] [name_f]Mae[/name_f], [name_u]Saylor[/name_u] [name_u]Lynn[/name_u], etc.
I am guessing it was be [name_m]Say[/name_m]-lor and [name_m]Say[/name_m]-ler maybe?
