<p>Is there a space such that it doesn't have any deformation but its space of first order infinitesimal deformations is non trivial?</p>

<p>Such germs of spaces exist. See Section 7.6 of Ravi Vakil's paper <em><a href="http://arxiv.org/abs/math/0411469" rel="nofollow">Murphy's law in Algebraic Geometry</a></em>.</p>
