Ralph Shaa
Shaa ( pronounced and sometimes spelled "Shaw" ) played a minor but pivotal role in the Wars of the Roses by preaching a sermon on June 22 , 1483 which claimed that Edward IV ( as whose chaplain he had served ) had already been betrothed to Eleanor Butler at the time of his marriage to Elizabeth Woodville , and that Edward V was therefore illegitimate and had no claim to the throne .
