Hello!!
I want one of those three as a middle name to honor my grandmother. But I am having trouble thinking of a good first name!
I perfer names that are a bit alternative, but not so out there that no one has ever used them. Not to many vowel sounds 
Also, have you guys had one trouble with one person/side of the family getting upset that you chose family names from one side and not the other?
From your signature, I think Kestrel [name_f]Lauren[/name_f] is lovely.
As far as the family names, my daughter’s middle name is [name_f]Dawn[/name_f], for my husband’s late grandpa [name_m]Don[/name_m]. No one has said a word to me on my side, if they’re offended they’re kind enough not to mention it. I don’t think you need to worry about it too much if your family is otherwise typically reasonable.
My favourites on your list are [name_f]Maisie[/name_f] [name_f]Laurel[/name_f] and Kestrel [name_f]Lauren[/name_f]. Other first name suggestions if you choose to keep looking…
[name_f]Mercedes[/name_f]
[name_f]Tenley[/name_f]
[name_f]Ziva[/name_f]
[name_f]Amoret[/name_f]
[name_f]Delta[/name_f]
[name_u]Brinley[/name_u]
[name_f]Maisie[/name_f] [name_f]Laurel[/name_f]!!!
I adore the name [name_f]Laurel[/name_f].
Although I don’t know the last name I like the idea of:
[name_f]Eileen[/name_f] [name_f]Lauren[/name_f] ("[name_f]Ellie[/name_f]")
[name_u]June[/name_u] [name_u]Laurie[/name_u]
[name_f]Audrey[/name_f] [name_f]Laurel[/name_f]
Or my favorite…
[name_f]Anna[/name_f] [name_f]Laurel[/name_f]
Pronounced with the emphasis on the latter half of “[name_f]Laurel[/name_f]”
