I think it depends on the name. For characers I like to use alliteration, because its catchy, but with real baby names, I’m a little picker about it. One of my favourite combos for a long time was [name_m]Rhett[/name_m] [name_m]Remington[/name_m] [name_u]Walker[/name_u]. I decided there were too many rrr’s in there though and took it off my list. Another combo I liked in theory for a girl was [name_f]Susannah[/name_f] [name_f]Johannah[/name_f] (I know, I know). When I say it out loud, they sound different, but written they look too close to the same name for me.
