Simon's children are mentioned in the 1595 will of his brother William, which doesn't state that Simon was dead but doesn't imply he was alive, either. The author makes a case that "Simon of Kerdeston in Norffoke" was the Simon Feake of Kettelston, co. Norfolk, tanner, whose undated will was probated 12 Jun 1570 in Norwich, his brother Robert being named executor. The will names his wife Alice and son John and mentions other unnamed children.
Based on his father's will, the author believes that Simon was his father's second son. Based on Simon's own will and that of his brother William, the author suggests he had 4 children when he wrote his will.
