Undefined references in Edmund Tudor, 1st Earl of Richmond

edit

Hi, in this edit you used an {{sfn}} template to call a reference "Anselm 1726". Unfortunately you have not defined the reference, so not only can nobody look it up, but the article is also added to Category:Harv and Sfn no-target errors. If you correct this then that would be great. DuncanHill (talk) 20:07, 22 December 2022 (UTC) And you've done the same thing here on Catherine of Valois.
