Our daughter's name is Yvonne Lorene. Our son's name is John Damien, pronounced 'dah-mee-ehn' in French. My husband's family is from Louisiana, that's where we get the Yvonne & Damien. Lorene and John are from my family.
What about Katheryn Yvonne or Katheryn Lorene? My niece is named Faith Marie... Katheryn Faith or Katheryn Marie? My family's names don't seem to roll off the tongue well as first names with Katheryn as a middle name. To be honest, once we decided on Yvonne and Lorene I couldn't decide which one to use first. First I wrote the names in different orders, then I waited until I was alone one day and started yelling the names repeatedly one way and then the other as if I was calling down the street or yelling as if my child was running towards the street. Lorene Yvonne and Yvonne Lorene. When I accidentally yelled out Loronne Yvene when I got tongue-tied, I chose Yvonne Lorene! I have never mispronounced Yvonne Lorene, so far :) Actually, now Loronne Yvene sounds pretty. It would be different. Katheryn Yvene or Katheryn Irene are both pretty, too.
For boys: not much help here. We do have Xavier, Edmund, Jeromey and Cody. My nephew is Joseph Eli. Oh, I have an Uncle Orville, but he goes by Junior. My son has a classmate named Roman and one named Rafael (Rafe for short). Hmmm. Brainstormong now: Jordan, Trevon (tray-vohn), Trey, Javier, Devin, Pierce, Forrest, Cranston, Quentin... Some of my kids' classmates :)
Good Luck and have fun!
