Help with a Unique Boy's Name?

Hello all. DH and I are trying for a 4th and are stumped on a name.

We like unique, but real names. Nothing made up or overly popular.

My favorites are:

[name_m]Holt[/name_m]
[name_m]Bear[/name_m] (though I admit it should probably stay a GP)
[name_m]Shepherd[/name_m]
[name_m]Wilder[/name_m] ([name_u]LOVE[/name_u])

DH has an affinity to [name_m]Theodore[/name_m] [name_m]Roosevelt[/name_m] and [name_m]Theodore[/name_m] is where his heart is set.

[name_m]Theodore[/name_m] [name_m]Holt[/name_m] is our top choice right now, though I prefer [name_m]Theodore[/name_m] [name_m]Wilder[/name_m].

Any suggestions to add to our (too) short list?

Big sibs are G!deon, Ar!e, and R!ver (girl).

[name_m]Theodore[/name_m] [name_m]Holt[/name_m] is a magnificent combo. If you’re not certain about [name_m]Theodore[/name_m], maybe another [name_u]Theo[/name_u] name, like Theodric, Theodosius, [name_m]Theon[/name_m], [name_m]Theron[/name_m], or [name_m]Theophilus[/name_m].
