Hi, Stella. I may be of help to you. There is the site http://www.passagetoellis.gr
which relates to emigration to the States from the municipality of West Mani, Greece. Some of the surnames you are researching are certainly contained in its database. You may make queries using the virtual Greek keyboard supplied. Use the keywords "ταβουλαρη", "παπαγιαννη", "μανταλη" and likewise with the rest.
