If we have a boy, I'd really like to name him Robert, after my dad. We've thought about using the nickname Rory since my dad used Bob, and brother uses Rob. The only issue is that our last name also starts with Ro. Too much of a tongue twister? It's really important to me, but I also don't want the name to sound funny. DH doesn't mind the alliteration.
Other boy names that we're considering are Henry, Owen, and Finn. For a girl we like Jane, Margaret, Elizabeth, or Anna. Big brother is Jack (John, but we only use Jack).
Any input or other ideas?
