I think it could well be a mash-up or “smoosh” name. This has been common in Mormon/LDS world for a long, long time. I have Mormon relatives in their 60s and 70s with smoosh names. When someone with a smoosh name is paired with someone else with a smoosh name for a whole new smoosh name, the fun goes on and on! ;)
Actually, it’s really quite interesting. If anyone here hasn’t checked out the Utah Baby Namer, you’re in for a treat.
