Re: Attn: Serafina Starstrider
I like the way you think. Let's see:
Henrietta works for me. The sister directly above William is named Caroline, but she is also his favorite sister, so that could work as an MN. I'm also a fan of Anne Marie Livia and Gaiana. Other family names include Adriana Isabel Cassandra and Augusta.
Henrietta Livia Caroline
Henrietta Marie Isabel
Livia Caroline Cassandra
Livia Augusta Anne
Any other combo you can think of...I feel like we might be missing one name that would perfectly tie everything together. What do you think?
As far as boys names go, I have used Tristan twice already (the King and the Crown prince) so we can either retire it or consider it one of those family names that needs to be passed on through the generations. Sebastian and Leopold are William's middle names, so we could name a son one of those, but probably not both. I like the other names on your list as well. Some combos:
Phineas Tristan Percival
Cornelius Sebastian Maximilian
Leopold Phineas Tristan
Sebastian Frederick Maximilian
Phineas Marcus Leopold
Anything look good? Any other ideas?
