[Quoting summary from Source:Parker, Francis J. Genealogy of the Ainsworth Families in America, p. 24 for brevity]
"In 1790, Jacob, the son of Thomas, applied to the Court to have him put under guardianship, alleging that by reason of the infirmities of age he had become non compos mentis. The Court called upon the selectmen of Brookfield for their opinion of Thomas's capacity, and they agreed in declaring him non compos, whereupon Jacob was appointed guardian to this father.
"Very soon, Thomas, by his next friend, applied to have the guardianship removed; and his application described Jacob as an undutiful and unthankful child (Jacob was 48 years old then). The Court examined Thomas, and in April, 1791, declared him competent to manage his own affairs, and ended the guardianship."
26 Oct 1790: Petition of "Jacob Ainsworth of Sturbridge ... Said Thomas Ainsworth is now possessed of a small Estate which may be a Mean[s] of Supporting him in his old age, but there is Danger of the same being totally lost & Squandered..."
6 Dec 1790: by Pliny Merrick his next Friend: "the cause for which Jacob Ainsworth was appointed guardian to the said Thomas does not now exist ... conceives your Honour has been misinformed ... used with severity and unkindness by his s'd guardian ... under the controul of an undutiful and unthankful child".
5 Apr 1791: Judge's decree: "...now in Possession and has the exercise of his mental Powers & Faculties - it is therefore considered by Me that the said Letter of Guardianship be and it is accordingly revoked..."
