Persons, citing Boyan, mentioned a document that reads: "A warrant was issued by the Lord Lieutenant of Cornwall to inquire about the division of lands of the late Francis Tregian, Recusant, in May 28, 1619" indicating that he died prior to that date. Ironically, living at Fleet Prison allowed Tregian a modicum of style and he maintained a library of "many hundred books" according to Alexander Harris, the prison warden. Probably due to unpaid debts, the library was dispersed and nothing is known about its eventual disposition. After Tregian's death his mother accused him of defrauding her by furtive financial transactions, and another "kynsman," John Arundell, accused him of financial impropriety. Thompson concludes that Tregian's imprisonment was probably much more about improper handling of finances than it was about recusancy.
