Thanks to a family friend; Coe became interested in bluebirds a few years back. He gave him a few bluebird houses and since then Coe has been watching the birds call it home each Spring.
He said "I don't know I just thought it was a good name for him."
I then proceeded to tell him that Rufus was my grandpa Castor's name. He just went by Paul (his actual middle name) his whole life.
From there Coe decided that "Rufus' wife" (as Coe would call the female bluebird) should be named "Della". (My grandmother's name.)
