I thought I knew the hobbit family trees pretty well. But a google search for "Eglantine Took" brings up this Wiki entry:
Eglantine Took, or Eglantine Banks, a fictional character; mother of Peregrin Took, second cousin, once removed, of Haldomere Banks Who the heck is "Haldomere Banks"? He's not in the Family Trees in Appendix C. And I don't find him in People of Middle-earth Family Trees either. Has anyone ever seen a reference from canon to a "Haldomere Banks" or did somebody's fanfic OC make his way into a Wikipedia article?
