Title: On m.a.d. \(s_0\)-nonmeasurable sets with a small dominating subfamilies

Abstract. We show that \(\mathfrak{d}=\aleph_1\) 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).
