Hello! My husband and I will be TTC very soon and are brainstorming baby names. I need the baby names to start with certain letters to honor relatives that have passed away. Our last name is common and ends in -er.

Letters I need to use are:
C, M, or R.
Please help me brainstorm names! I definitely want use the C for a first or middle name.
These are names that I like so far: Madelyn (girl), Riley (girl), Carter (boy), Max (boy).
Side note, Does Carter ----er (our last name) sound funny?
