Note his wife's first name, "Kirsten".
Well, all this time, I've thought the first name in the inscription pictured below was simply someone named "Christen" who forgot the "i" when inscribing his own name.
Now, I'm wondering if it may have been Kirsten, just spelled differently - "Chrsten". Or more likely, miss-spelled. Note, the last name is spelled differently too, it's what makes me think it is just a miss-spelling. I've seen lots of historic inscriptions where old time pioneers or outlaws have miss-spelled their own names. Heck, just look at the "Mat" Warner inscription in this trip report for an example. I took that picture near Robbers Roost spring, which isn't all that far from Bluff and the wall it is inscribed on is covered with old pioneer names from the greater surrounding area. Anyway, interesting possibility.
