Are there any Markham genealogists on WikiTree

Question

I am reviewing the line to Margaret Canmore, Saint Margaret of Scotland, down through the profiles to me.  

The relationship finder says that she is my 28th Great Grandmother. 

 However, in this line, there is listed a William Markham MP as a 14th Great Grandfather.  The profile has the 'History of Parliament' as a resource on William's profile page.  But, the resource clearly states that William died with only one heir, that being a Anne Markham. (Not an Isabel as stated on the profile).  [http://www.historyofparliamentonline.org/volume/1509-1558/member/markham-william-1533-7071]

The source also states that his daughter 'Anne' married a Nicholas Timperley but that she died without heirs and that this "branch of the Markham family became extinct." (and this is referenced as 'PCC 32 Holney ptd. Markham, 87-90.'

So, It looks like this whole line has been based on using a tree that has no references...perhaps a tree a ancestry.com?... since I have searched other sources with no information on any "Isabel Markham.

Any help would be very much appreciated.

Thank you,  Scott

I am presently reviewing all of my work done on my relationship to any royalty lines on Wikitree.  Right now I looking at my notes on Henry II Plantagenet..most from Wikitree.  

My notes show that the 'relationship finder' reveals that he is my 27th great grandfather.  However, William Markham MP is also in this relationship line as the father of an 'Isabel', mother of William Skelton.  

If I use the one and only source that I have on William Markham Mp c1526-1571 that says "his line is extinct", I must delete this relationship as well (in my own records)...most likely this line will stay the same on wikitree since so many others would be effected too?
