Sibset!

What do you think of the following sibset?

[name_f]Kassandra[/name_f], Eythan, Sebastiaan and [name_m]Adrian[/name_m]
[name_f]Kassandra[/name_f] (kah-san-drah)
Eythan (ee-thin)
Sebastiaan (sah-bass-tin)
[name_m]Adrian[/name_m] (ay-dree-in)

[name_f]My[/name_f] politeness depends entirely on whether or not this is a hypothetical sibset or a real sibset.

I don’t care for the shared endings among the boy names.

As far as the alternate spellings, I prefer [name_f]Cassandra[/name_f], [name_m]Ethan[/name_m], and [name_m]Sebastian[/name_m]. I also feel [name_m]Ethan[/name_m] might be a bit tame for siblings [name_f]Cassandra[/name_f], [name_m]Sebastian[/name_m], and [name_m]Adrian[/name_m].

Its a real sibset.
