We need a name for Noelle's sibling! We've been going back and forth and just can't find anything we LOVE. Any comments and suggestions would be appreciated. We are Roman Catholic and Biblical or Saints names would be a plus

DD1 is Noelle Marie Green.
Here is our list so far. There's just nothing jumping out at us.
Blythe
Britta
Caroline (would people think we named her after my MIL, Carol?)
Celeste
Genevieve (Strongly dislike the nn Genna)
Jillian
Liesl
Madeleine
Naomi
Re: Sibling for Noelle??
I love Celeste, and Madeleine if you are pronouncing it with -leen ending. I also like Genevieve and Blythe.
Have you consider Miriam, Evelyn, Theresa?
I love Naomi, Blythe and Leisl.
I probably would assume Caroline was after your MIL; I'm actually avoiding the name because it's too close to my grandma's name, Carolyn (and then later I found out she was named for a Caroline, so...definite connection in my family).
Suggestions: Jane, Magdalena, Vivian, Gretchen, Heidi, Sonya, Charlotte, Joy, Serafina, Cecily, Amelia
Theresa (nn Tess or Tessa).
BFP #2 11/6/13 - EDD 7/14/14 - blighted ovum discovered @ 7w - natural m/c @ 10w3d
BFP #3 5/25/14 - EDD 2/1/15 - Hoping this is our 2nd little owl
A/S findings: Baby is a girl! EIF found on heart
but maternit21 came back neg for chromosome disorders!!
(Which I think is an interesting choice due to both its and Noelle's association with the Christmas story. FWIW, Liesl is German for Elizabeth, who was also the mother of John the Baptist according to the book of Luke. When she saw her cousin Mary who was pregnant with Jesus, she exclaimed that Mary was blessed among women to be the mother of her Lord.)
