This reminds me of a family I know. The two boys have INCREDIBLY unusual names, so unusual to the point where I can’t say the names because they are the only people with their names in the entirety of [name_u]New[/name_u] Zealand (where we live)
The third sibling? A girl…
Named [name_f]Olivia[/name_f] [name_f]Grace[/name_f].
