What are your daughters names? It may help people to make suggestions to you as it'll give an idea if you are quite traditional etc!
My boys are Owen and Alex and if this is another boy he'll be Jake!
I can't help much. With my son we had the girl name picked out days after we got our bfp. The boy name didn't come to us until well into the third trimester. Middle name was picked early on but it's a family name. We settled on Holden Christopher. With this baby we have picked Calliope Rose for a girl and Jaiden Elliott for a boy. We don't really have any other names we agreed on that we liked first and last combos.
