Who marryed Edmond Mortimer, Earle of March:
Edmond had Issue, Roger, Earle of March;
Roger had Issue, Edmond, Anne, and Elianor

Salisb. This Edmond, in the Reigne of Bullingbrooke,
As I haue read, layd clayme vnto the Crowne,
And but for Owen Glendour, had beene King;
Who kept him in Captiuitie, till he dyed.
But, to the rest

Yorke. His eldest Sister, Anne,
My Mother, being Heire vnto the Crowne,
Marryed Richard, Earle of Cambridge,
Who was to Edmond Langley,
Edward the thirds fift Sonnes Sonne;
By her I clayme the Kingdome:
She was Heire to Roger, Earle of March,
Who was the Sonne of Edmond Mortimer,
Who marryed Phillip, sole Daughter
Vnto Lionel, Duke of Clarence.
So, if the Issue of the elder Sonne
Succeed before the younger, I am King

Warw. What plaine proceedings is more plain then this?
Henry doth clayme the Crowne from Iohn of Gaunt,
The fourth Sonne, Yorke claymes it from the third:
Till Lionels Issue fayles, his should not reigne.
It fayles not yet, but flourishes in thee,
And in thy Sonnes, faire slippes of such a Stock.
Then Father Salisbury, kneele we together,
