Lurlene doesn't look much like Lorelei to me either. I'd have to see some convincing evidence of how that came about.
Lurlene looks to me more like an invented name from the heyday of Marlene, Darlene, etc., so maybe 1920s-40s. The first syllable may have been from Lura, which was not exactly a common name at that time, but was regularly used.
I've seen a few rhyming names like Shirlene, Myrlene, Pearlene.
