^Sources tend to confuse and conflate the two brothers. There is a "Frederick Mostyn Parks" listed in Sports Reference as the Olympic medalist. There is "F. Parks" and "Frank Parks" listed in The New York Times for the exhibition matches in the US. The obituary by the Polytechnic Boxing Club is about "Frank Parks". Other sources use a pastiche of information on each in their records. On January 2, 2011, Elaine Penn, the University Archivist for the University of Westminster wrote: "I have just discovered that Fred and Frank Parks are brothers. I quote from the Poly Boxing Club report in the Polytechnic Magazine for December 1908 (page 173), regarding an Open Competition promoted by the City Police AC: 'Fred. Parks (Frank’s brother) was our other member who showed up most conspicuously, as he beat three men in the earlier bouts and succumbed in the final only through not having enough physical strength to meet a comparatively fresh man who had just had the benefit of a bye. We must say that we were delighted with the manner in which Fred boxed during the whole of the evening, and we feel certain that before long he will become a boxer with reputation very little short of that held by his brother Frank.'
