What would you name [name_u]Jean[/name_u]'s brother? Middle name would probably be a family name. Options are [name_m]Oliver[/name_m], [name_m]Daniel[/name_m], [name_m]Julian[/name_m], and [name_u]James[/name_u].
Any of those work nicely. My favorites are [name_m]Oliver[/name_m] and [name_m]Julian[/name_m], but you might want your kids to have their own initial and not both start with J.
[name_u]Jean[/name_u] and [name_m]Daniel[/name_m] sound nice together.
I like [name_m]Oliver[/name_m] best of the options! [name_m]Julian[/name_m] is also handsome but I wouldn’t use two J names together in a sibset, personally.
