Thomas married twice. His first wife was Eleanor Doreward, daughter of John Doreward, Sheriff of Essex & Hertfordshire, Speaker of the House of Commons and his wife, Katherine Wolcot. They married before 1418. They had two sons:
Thomas' father-in-law bought the Manor of Stanway in Essex from Thomas' father in 1401. The manor had come into the Knyvett family control when it had been the legacy of Thomas' mother from her parents. The manor returned under the control of the Knyvetts when it was bequeathed to Thomas and Eleanor when her father died in 1420. However, the title to Stanway was still in contention in 1441, when Thomas sued John Doreward, who presumably was a relative of Eleanor, who had died some years earlier.
Inheritance from his Father
Thomas' father died in 1419, and as his primary heir, Thomas inherited the manors of Ramsden-Belhouse in Essex, Newington Belhouse in Newington, Kent and Castelins in Groton, Suffolk.
