[1] The son of Bishop Edward Worth,[2] and Susannah Pepper, daughter of Denis Pepper, a cousin of the Earl of Cork, and brother of the noted judge William Worth, he was educated at Trinity College, Dublin.
[8] Religious differences played a large part in his own early life.
His father was a Protestant of strongly Puritan leanings, with no sympathy for either Baptists or Quakers.
This caused a breach between the couple which was never healed: in his last will his father urged his mother to repent for her unorthodox beliefs.
Only two are known to have survived into adulthood, Michael and Edward Worth (1678-1733), the noted physician and book collector.
