Edmund Shakespeare b 1580. They christened him on May 3 , probably in honor of his Uncle Edmund Lambert. Edmund did not make a great reputation for himself as an actor, but, in all fairness, cruel fate, and not his poor acting abilities, was likely the reason. Edmund died in 1607 -- not yet thirty years old. He was buried in St. Saviour's Church, in Southwark, on December 31 of that year. His funeral was costly and magnificent, with tolling bells heard across the Thames. It is most likely that William planned the funeral for his younger brother because William would have been the only Shakespeare wealthy enough to afford such an expensive tribute to Edmund. Records show that the funeral was held in the morning. It is probable that the morning funeral was arranged so that Shakespeare's fellow actors could attend the burial of Edmund.
He may have had a son, Edward, born 1607, the year of his death.
