Lichtensz is not a name -- it looks as though the end was cut off and it should be Lichtensztajn or possibly Lichtensztern. I've only investigated the possibilities for Lichtensztajn.
We enter the names as they were signed, abbreviations and all. You are right to look for names that begin with Lichtensz, and thank you for reminding your fellow researchers of this fact!
