[name_m]Hi[/name_m]! I’ve been wanting to change the last names for my MCs and their family, but I’m having a hard time finding one that goes with all of their names. It’s a Southern Gothic story set in the real world and modern times. All suggestions welcome!

The names:
(unnamed dad, will be a serial killer if that helps, first name ideas welcome)
[name_f]Misty[/name_f] (mom)
[name_u]Brennan[/name_u] (oldest son)
[name_f]Cora[/name_f] (oldest daughter)
[name_u]Tierney[/name_u] (middle daughter)
[name_f]Abigail[/name_f] (youngest daughter)

Thanks!

Their last name could be:
Blood, Blackwood, Crabtree, [name_m]Creed[/name_m], [name_m]Gunn[/name_m], or something common that sounds good with all their names like [name_m]Crawford[/name_m], [name_m]Turner[/name_m], or [name_m]Gilbert[/name_m].
