The possible identity of Thomas' other children have been picked up from various Census entries and parish records.

With regard to Henry below, a family link is implied by the fact that his daughter Mary Eliza later stayed at North Curry, Somerset, described as the niece of Thomas's son Thomas.

John's connection is implied from the 1831 Dorset Poll book where Thomas jr & John Plowman of North Curry, Somerset and Henry Plowman of Fordington all have an interest in the same property in Cattistock.
