Surname help??

I need some suggestions for last names for my two characters, [name_u]Arden[/name_u] and [name_m]Eli[/name_m]. [name_u]Arden[/name_u] used to be called [name_f]Jane[/name_f], and I liked [name_f]Jane[/name_f] [name_m]Palmer[/name_m], but now that some major plot details have changed and [name_m]Eli[/name_m] has a real name, I have decided that I like [name_u]Arden[/name_u] better. The characters are not related so I need suggestions for both of them. Thanks so much in advance and I wish you all the best of luck with your own writing!

[name_u]Arden[/name_u] Whittingham & [name_m]Eli[/name_m] [name_m]Baxter[/name_m]

[name_m]Eli[/name_m] [name_u]Sinclair[/name_u]
[name_m]Eli[/name_m] Kline
[name_m]Eli[/name_m] Mueller
[name_m]Eli[/name_m] [name_m]Farrar[/name_m]
[name_m]Eli[/name_m] [name_m]Gage[/name_m]
[name_m]Eli[/name_m] Tessaro
[name_m]Eli[/name_m] [name_f]Garland[/name_f]
[name_m]Eli[/name_m] [name_m]Olson[/name_m]

[name_u]Arden[/name_u] Snyder
[name_u]Arden[/name_u] Hollaway
[name_u]Arden[/name_u] Molansky
[name_u]Arden[/name_u] [name_u]Storm[/name_u]
[name_u]Arden[/name_u] Dubois
[name_u]Arden[/name_u] MacIntosh

These names sound British… so I’m going off of that!
Renoir (I think this is the coolest last name ever)
[name_f]Concorde[/name_f] (also super cool)
[name_f]Hope[/name_f] these help!
