This is an example of people continuing to copy "unproven" genealogies. There are no sources to support the parents on any of the websites such as Ancestry, Geni, Myheritage. I would suggest that the first thing you do is acknowledge that the parents shown are incorrect for several reasons.
Even with a birth of 1785, the parents were not married until 1786 and that has a source, whereas, none of the data for Lenner has a source, other than a headstone with no indication of a maiden name Also, a quick research, there appears to be a "Lena" who married a Isaac Allen, there are several stories of Isaac and Lena Allen living in Lycoming, Pennsylvania and their relationship with the Reading family. Many of the trees cite a marriage record that does not include a Lenner or Lena, but an Elizabeth Rush.
Sometimes removing the unproven data will help you find the answers you are looking for....
