Could you help me find my family crest?

My family has a rather strange name. Our current last name is Consider, which is an americanized version of Considere, borne by the farthest ancestor I've been able to find, a man who emigrated from France with his wife. I'm trying to find our family crest, if there is one, but none of the "family crest look up" websites have our last name. Any information would be appreciated.
