Thomas Helwys was born in Gainsborough, from Edmund and Margaret Helwys who were descendants of an old Norman family. Edmund had sold his land in Lincolnshire and Northamptonshire and had taken a lease on Broxtowe Hall in Bilborough parish. In 1590 when his father died, Thomas Helwys assumed control of the estate, but in 1593, left the care of the estate in the hands of his father's friends and began studies in law at Gray's Inn, one of the four Inns of Court in London.
