As of this date, R' E HaLevi Ottingen has no known living yDNA descendants listed in GENI, the most recent died in 1922. However, there could be descendants who are not listed on GENI. yDNA testing of one or more of these descendants would be a valuable addition to this family tree's knowledge base. If a person reading this is qualified to make the test and is willing to do so, please reply to this discussion.
