Baby names

We were set on names. But recently started going through some more. I've searched through many sites and just can't seem to find any that really stick out. We have an Alexis and an Oliver (Lexy and Ollie) so want something that has a Y sounding nickname. Not finding out the gender so need names for both. We like Mackenzie for a girl and Jo for a middle name girl. (I also like Sophia and Samantha) We like Benjamin for a boy and Wade for a middle name boy. I don't want this kid to have 5 others with the same name in their class.... Ugh just can't think of any. So tell me what your favorite baby names are. We're totally open. TIA :)
