Cover art for Dani California lyrics by Red Hot Chili Peppers

In Wikipedia I came to find this information, supported by the guy who wrote the lyrics. So Dani IS the same 'girl' in Californication. I'm posting the column about the origins of the song here:

"Throughout the song, lyricist Anthony Kiedis laments the early death of Dani, a poor, young Southern girl who eventually lived in California, became a mother and lived a hard, fast, unsettled life.[4] Kiedis has commented that the character of "Dani" is an embodiment of all the women with whom he has had relationships. The song narrates much of Dani's life, starting with her birth in Mississippi and apparently culminating with her death in the badlands of North Dakota.[5]

Dani first appeared in the 1999 song "Californication", which includes the lyrics "Teenage bride with a baby inside/Gettin' high on information" although the girl's name is not specified. She was next mentioned in the Red Hot Chili Peppers' 2002 single "By the Way" as "Dani the girl". It is also possible that the character is alluded to in the 1999 single "Scar Tissue" from the "Californication" album through the lyrics "Blood loss in a bathroom stall/Southern girl with a scarlet drawl" and "Push me up against the wall/Young Kentucky girl in a push-up bra." On the subject of "Dani California", Kiedis is quoted as saying: "When this funky groove came up it struck me as a perfect place to actually tell a story. It sort of revealed itself to me that it's been the same character, just kind of developing. At first I didn't realize that I was writing about the same girl."[6]

Guitarist John Frusciante utilized various instruments and effects devices in order to achieve the textures and treatments used throughout the song, including Mellotron, Moog effect pedals, and a Doepfer modular synthesizer, used for the filtering and processing of pre-recorded tracks. Although it is sometimes low in the mix, the main riff, (which is heard primarily in the first verse) plays throughout as an underlying tone."
