Hypothetical Sibset of 4

I’m wondering what my fellow nameberries think of the following sibset:

[name_m]Fabian[/name_m] “[name_u]Finn[/name_u]” (adopted)
DD1: [name_f]Minerva[/name_f] “[name_f]Mina[/name_f]”
DS1: [name_m]Seamus[/name_m] “[name_u]Shay[/name_u]”
DS2: [name_m]Coltrane[/name_m] “[name_m]Colt[/name_m]”

I wouldn’t ever use this sibset for real children but I’m interested to see if the names flow together and what else would work with those names. I may use them on some fictional characters.
