Title: On m.a.d. s0-nonmeasurable sets with a small dominating subfamilies

Abstract:
We show that d=ℵ1 implies the existence of maximal familiy of eventually different reals on Baire space which forms a nonmeasurable set with respect to an ideals generated by trees (perfect, Laver or Miller trees for example).
