A lot of Lithuanian surnames are adapted versions of Polish names, or sometimes, Bielorussian. This is because most Lithuanians did not adopt surnames until after the union of the Kingdom of Poland with the Grand Duchy of Lithuania, in which Poland was the dominant partner. Later the name endings were often changed to suit the Lithuanian language.
Adaskevicius looks like the Polish (or Bielorussian)Adaszkiewicz, which is probably a patronymic deriving from a diminutive of Adam.
Aglinskas looks like it might be from the Polish Oglinski.
Abraitis might be from the name Abraham with Lithuanian patronymic ending.
