on page 93 in this copy..it states that "... there bee certaine proofes
that the Princes were both living in the moneth of February following
the death of their father...and this is plaine in the Records of the

end quote

thanks to the american branch of r3 society i'm able to read titulus
regis on line.
http://www.r3.org/bookcase/texts/tit_reg.html

the princes are not specifically named herein.
titulus states...
" Alfo it appeareth evidently and followeth, that all th'Iffue and
Children of the feid King Edward, been Baftards, and unable to inherite
or to clayme any thing by Inheritance, by the Lawe and Cuftome of
Englond."

does anyone know what/where else buck could be referring to in regards
to "certaine proofes" to be found in the parliamentary rolls of feb.
1484?

or where i might find, hopefully online, or perhaps in a book the text
of these records of february 1484.
