Looking at the CDOJ file for Matthew Knoefler, I wonder if his “Haven Rain” tattoo actually spells “Heaven Rain.” That would make a lot more sense. It sounds like it could be a name, possibly his daughter’s; maybe it’s her date of birth tattooed on his other arm.
Shrug.

It could be, or it really could be “Haven”. I love that name, actually considered it when I was pregnant, and I’ve heard of people with that name as well. On the other hand, I guess it could be a typo, too.
It’s the middle name that makes me wonder if it’s Heaven and not Haven. “Heaven Rain” sort of go together, in a cutesy way. Like “Misty Dawn.”
