I love [name_m]Theodore[/name_m], but I’m struggling to find a middle name I like with it. I’d like something a bit quirky, maybe literary or from nature. The only one I kind of like is [name_m]Theodore[/name_m] [name_u]Finch[/name_u], but apparently that’s also a character from a YA novel. Any help would be appreciated! 
Some ideas:
[name_m]Theodore[/name_m] [name_u]Sage[/name_u]
[name_m]Theodore[/name_m] [name_u]Linden[/name_u]
[name_m]Theodore[/name_m] [name_u]Rowan[/name_u] (although the R’s run into each other a bit)
[name_m]Theodore[/name_m] [name_u]Zephyr[/name_u]
[name_m]Theodore[/name_m] [name_m]Caspian[/name_m]
[name_m]Theodore[/name_m] [name_u]Onyx[/name_u]
[name_m]Theodore[/name_m] [name_u]Flynn[/name_u]
[name_m]Theodore[/name_m] [name_u]Sequoia[/name_u]
[name_m]Theodore[/name_m] [name_m]Sylvan[/name_m]
[name_m]Theodore[/name_m] [name_f]Sparrow[/name_f]
[name_m]Theodore[/name_m] [name_f]Starling[/name_f]
I think [name_m]Theodore[/name_m] [name_u]Finch[/name_u] is super cute and quirky!
Here are some I thought of:
[name_m]Theodore[/name_m] [name_u]Jude[/name_u]
[name_m]Theodore[/name_m] [name_m]Redd[/name_m]
[name_m]Theodore[/name_m] [name_u]Bo[/name_u]
[name_m]Theodore[/name_m] [name_m]Flint[/name_m] (close to [name_u]Finch[/name_u]!)
[name_m]Theodore[/name_m] [name_m]Graham[/name_m]
[name_m]Theodore[/name_m] [name_u]Rhys[/name_u]
[name_m]Theodore[/name_m] Ness

Haha, my sister’s favorite boy names are [name_m]Theodore[/name_m] and [name_u]Finch[/name_u] because of the same book 
She says she’d name her child [name_m]Theodore[/name_m] [name_u]Finch[/name_u] but it wouldn’t exactly be good luck
[name_m]Theodore[/name_m] [name_u]Finch[/name_u] is super cute
I have:
[name_m]Theodore[/name_m] [name_m]Calix[/name_m]/Calyx (from the selection series [name_m]Maxon[/name_m] [name_m]Calix[/name_m] Shreave and Calyx is a part of the human body, I think in the kidneys)
[name_m]Theodore[/name_m] [name_m]Ambrose[/name_m] (from the [name_u]Storm[/name_u] and [name_f]Silence[/name_f] series on Wattpad)
[name_m]Theodore[/name_m] [name_m]Wolf[/name_m] (various)
[name_m]Theodore[/name_m] [name_m]Ezra[/name_m] [name_m]Jack[/name_m] (various)

I think you should just use [name_u]Finch[/name_u]! Its adorable and the flow is nice
If it helps I had no knowledge of the YA reference and think [name_m]Theodore[/name_m] [name_u]Finch[/name_u] is excellent!

[name_m]Theodore[/name_m] [name_u]Finch[/name_u] is fantastic! I doubt it’s a widely known association.
[name_m]How[/name_m] about [name_m]Theodore[/name_m] Swift or [name_m]Theodore[/name_m] [name_f]Firth[/name_f]?
that character is who made me fall in love with the name [name_m]Theodore[/name_m]! I also love the combo [name_m]Theodore[/name_m] [name_u]Finch[/name_u], but I’m not sure I’d use it because of the character. [name_m]Even[/name_m] though I love him, I definitely wouldn’t want a child named the same thing as him (as a pp has said, it wouldn’t be a very lucky name)
However, as others have said, [name_m]Theodore[/name_m] [name_u]Finch[/name_u] is not a very well known character. You could 100% use it, and not many people would probably associate it with him.
[name_m]Theodore[/name_m] [name_m]Fox[/name_m] is my current favorite combo, and I think it’s slightly similar to [name_m]Theodore[/name_m] [name_u]Finch[/name_u].
Other combos (if there are any repeats, I’m just seconding the suggestions!):
[name_m]Theodore[/name_m] [name_f]Snow[/name_f]

I’m not aware at all of the literary reference but [name_m]Theodore[/name_m] [name_u]Finch[/name_u] is very cute. Perhaps, however, you’d prefer [name_m]Theodore[/name_m] [name_u]Finn[/name_u], [name_m]Theodore[/name_m] [name_u]Flynn[/name_u], or [name_m]Theodore[/name_m] [name_u]Finley[/name_u].
Other names that popped up in my mind were [name_m]Theodore[/name_m] [name_m]Wolf[/name_m] and [name_m]Theodore[/name_m] [name_m]Fox[/name_m].
My dream combinations were always [name_m]Theodore[/name_m] [name_u]Lindsey[/name_u] and [name_m]Theodore[/name_m] Catesby, myself!
