Can someone tell me who the hell these ghouls are?

[I hate everything.]

Who are the Ghouls that keep respawning with names like Mr. & Mrs. Rose and Dougles.

Named feral ghouls are just random encounters, according to Wiki...

The Sole Survivor can sometimes stumble across a pack of named feral ghouls. Their names are Mr. Donoghue, Mrs. Donoghue, Mr. Sumner, Mrs. Sumner, Mr. Parker, Mrs. Parker, Rosa and Rosa's son. These are all the names of the Sole Survivor's neighbors in pre-War Sanctuary Hills. Strangely, this is a repeatable encounter and can be seen many times, even if the ghouls have been killed.
