Hello,
My Aunt married Fred Ulberg from Tula'ele...Tuluaele is between Lepea and Vaiusu and in the Vailoa area...same area which you are searching. They had several children and several are several of them still living there. Daughter Lou Petersen, and Katherine live at the same place they've lived in for years. Another daughter Theresa lives on Maui, 2 other daughters live in NZ (Anne and Matalena)live in NZ and the boys Paul and William live in Samoa. I have not been in touch with them for a couple of years, but can if you need. Hope this helps
