Deletion of Genealogical relationships of Prime Ministers of the United Kingdom

Comment: I haven't decided how to vote yet, but I think the keep votes are less than convincing so far.  If this topic is much-discussed for the Cecils, can we see a source that discusses it for the Cecils?  Yes, many readers are likely to find this interesting, but that's not the issue here -- notability is the issue.  The one source cited here, Bloomfield, has been reviewed by Agricolae and found not to focus on this topic, and in any case the |GNG generally requires multiple sources, not just one.  Are there other sources to demonstrate notability

Comment: for my same (losing) arguments at Wikipedia:Articles for deletion/Genealogical relationships of Presidents of the United States. |Good sourcing ''ipso facto'' leads to |notability

Comment: both as on a non-notable topic and as a morass of |original research, synthesis and |poor sourcing
