We show that the dimension of any component of the Hilbert scheme of space curves (of degree d) is bounded below by 4d. We find components where the general point represents a nonlocally Cohen-Macaulay curve which is not a disjoint union of a locally Cohen-Macaulay curve and a zero dimensional scheme.
