Henry Harrison Lawrence had Thomas Davidson Lawrence as father. You created Henry Gravidson Lawrence as father. Then changed the father of Henry Harrison to Henry Gravidson, which is fine, but you need to make sure the documentation Is included on Henry Harrison, Henry Gravidson, and Thomas Davison's profiles with that source.
You can edit a profile that has a different PM that is open to editing. That is part of the Collaborative part of the site. When a relationship is being changed, frequently people will message the other person so they are aware of it, as well as Include your source, in case the other person has a different source or reason that they think your source is inaccurate. Your source is not a primary source, so there could be different sources. When a relationship is changed, which was done when the father was changed, the documentation needs to be included also.
