Baby Boy or Girl Mills, Sibling to Elias, Jacob, and Dylan

Taylor writes:

My husband and I are expecting our 4th child together soon- due date is April 17th to be exact. My husband's name is Jordan, my name is Taylor and our last name is Mills. We have 3 other children together: Elias Caden, age 6 and twin boys Jacob Harrison and Dylan Riley, age 2. With our previous pregnancies, names were not a big challenge at all. Eli's name was determined by 20 weeks, and with the twins, we walked into delivery with 2 names for each of them and decided there. This time around we are struggling, partly because we seemed to have used all the names we loved with our first three kids. To add to the situation, we decided that we would let the gender be a surprise.

Our 3 boys each have a family middle name, so names that are in the running to use are:
Francis, Nicholas, Oliver, Samuel, Isaac, Vincent, Matthew, Reagan, Adele, Juliette, Morgan, and Danielle/Daniella.

We have a very short list of names, but nothing we truly love so far:
BOYS:
Owen
Luke
Ryder
Griffin

GIRLS:
Leah
Abigail
Sofia
Madison
Kinley

Names we cannot use due to family/friend use:
Molly, Camden, Isabella, Katherine/Katelyn/Kate, Henry, Amelia, Evan, Ella, Savannah, Cooper, Lindsey, Hanna, or Lily
