I have in my possession two books written by a lady who I believe is now deceased. They are about her life. In the beginning she gives all of the information that she know about her mother and father. The surnames she references are Lahti and Oikersinen. I cannot locate Oikersinen?? They were supposed to have come from and island called Uuraan Saari south of Viepuri or Viborg. Any help will be appreciated as I would like to be able to put these in the families hands.
