A fitting middle name

I am in the middle of creating a character for a short story but I can’t find the ‘right’ middle name.
Her last name has to be [name_u]Day[/name_u] and I would like her first name to be Elísabet (an Icelandic variant of [name_f]Elizabeth[/name_f]). Hopefully it will remind the reader of the [name_u]Urban[/name_u] legens about [name_f]Elisa[/name_f] [name_u]Day[/name_u] without being too obvious. However, I am willing to chose another similar first name.

I already have a few ideas for a middle name:
[name_f]Ferelith[/name_f] ( Personally I really like [name_f]Ferelith[/name_f] but it is probably too close to Elísabet?)
What do you think? Any suggestions or comments?

I like [name_f]Elisabet[/name_f] [name_f]Gwyneira[/name_f] . [name_f]Gwyneira[/name_f] means blessed and snow.

I think [name_f]Elisabet[/name_f] [name_u]Harper[/name_u] [name_u]Day[/name_u] sounds great all together
