The family listed for this couple,  is a composite of persons by the surname Finley/Findley in NB and NS, that are known (or thought) to be brother and sisters.

        This man's name is thought to be Jonathan Finley, who was m. 24 Nov 1765, in New Port, New Port Co, Rhode Island, USA, to Jane Dennis. (data from Caroline White, CA / ref: IGI Rhode Island) Via Linda (below) she also said that Jonathan was in Georgia ca. 1779-81, which would be the time frame for Arthur Dennis' birth.

    Linda Keaton, (also of CA) has found records of military service for Jonathan in the Kings Rangers, during the Revolutionary War, also a land record for him in Shelburne, NS, in 1784. First saw mention of Jonathan Finley in Lorenzo Sabine's book, saying he and family of 10 persons went from New York to Nova Scotia at the peace and was given a grant by the Crown.

        Jonathan Finley came to Port Roseway as a Port Port Roseway Associate. The Minute book of the Association lists him as a tallow chandler whose family consists of a wife and 7 children. Sabine in "Loyalist of the Revolution" vol 2, states "Of Rhode Island. At the peace accompanied by family of ten [?] persons, he went from New York to Shelburne, Nova Scotia, where the crown granted him one farm, one town and one water lot."

Jonathan's grants were: Town lot "D" #1 in Patterson's division and Water lot "B" 12 in South Division. (I have not found the farm lot.].

No estate papers.

Not on 1786/1787 town and county tax assessments nor in 1791 poll tax.

Deeds:
= Book 1, p.9: Jonathan and Jane [the only deed which she is mentioned] sold  to Robert Houston for 18 pounds 13 shillings his water lot South Division B. #12 (This sale recorded again in Book 3-97 and was registered in 1781)
= Book 1, 167: Jonathan sold his town lot #B Patterson's with the house located there to John Anderson for 52 pounds, 10 shillings.
= Book 1: 417 Jonathan Finley, tallow chandler and soap boiler sold to Widget Stonehouse, merchant the western half of Town lot "D" in Patterson's Division for 8 guineas on 21 Aug 1784. [A guinea was worth 21 shillings]

(All property sold by 21 Aug 1784)

Based on other Port Roseway Associate members it is most unlikely that a Private would also be an established business person and landholder - such a person would  have automatically have been recruited at a higher rank. For more information about the group who organized themselves as Port Roseway Associates and pre-planned their settlement at Port Roseway see: Robertson, Marion, "King's Bounty. A Brief History of Early Shelburne Nova Scotia.

The marriages of what appear to be two of his children are found in Christ Church Anglican Church records.
