G,

>Ritva Lisa Rannisto. <vbg> Maybe I should take the Net and find her.

Lisa = Liisa ?

Could be a nice surprise to her if you find her but could be a hard on - maybe got married and lastname changed. If you remember a town where she lived then contacting to the church registry office may help or if you remember her parent (or her brother) names then looking for them may offer the easiest way. At least Rannisto is not a common lastname here. Good luck :)
