I’m realizing how many literary boy’s names end in -n! (Holden, [name_m]Dorian[/name_m], etc…)
[name_f][/name_f]Some more ideas:
[name_f][/name_f][name_f]Darcy[/name_f] (pride and prejudice)
[name_f][/name_f][name_m]Lowry[/name_m] (author lois lowry… maybe too unusual, but it sounds nice with peregrine!)
[name_f][/name_f][name_m]Wilbur[/name_m] (charlotte’s web – he is[name_f][/name_f] a pig, but a very endearing pig!)
[name_f][/name_f][name_m]Bennet[/name_m] / [name_m]Bennett[/name_m] (pride and prejudice again)
[name_f][/name_f][name_m]Ambrose[/name_m]
[name_f][/name_f][name_m]Casper[/name_m] / [name_m]Caspar[/name_m]
[name_f][/name_f][name_m]Ellis[/name_m]
[name_f][/name_f][name_m]Heath[/name_m]
[name_f][/name_f][name_m]Jasper[/name_m]
[name_f][/name_f][name_m]Henry[/name_m]
[name_f][/name_f][name_m]Louis[/name_m] (either pronunciation)
[name_f][/name_f][name_m]Wells[/name_m]
Good luck! [name_m]Peregrine[/name_m] ‘Pip’ is so cute!
