Middle name themes?

My absolute favourite name for a girl is [name_f]Aurora[/name_f] and for a boy is [name_u]Skyler[/name_u]. I feel like they fit a theme. I’d like for the middles (2 preferably but 1 also ok) to also fit a theme of their own. (i havent decided so i wondering what sort of ones you guys would think work!)

[name_f]TIA[/name_f],
[name_f]Abigail[/name_f]

[name_f]Aurora[/name_f] and [name_u]Skyler[/name_u] are very whimsical, magical names to me, so I think some more classic, maybe even vintage names would pair well with them. Off the top of my head, I think [name_f]Aurora[/name_f] [name_f]Margot[/name_f] [name_f]Pearl[/name_f] and [name_u]Skyler[/name_u] [name_m]Theodore[/name_m] [name_m]Clark[/name_m] would be nice.
