Curtis, I have never nailed down or read anything about the Scottish Co. as partners with Swift other than on here. I don't know what their source was on that. Maybe from one of the versions of journals I have not been exposed to yet. Swift was a merchant in Alexandria with a bldg that backed up to a dock/receiving area. His address is in Prather's book. Maybe he had trading partners? He was appointed consul by Washington to several Central/South American countries at that time. No telling who or where he traded with or imported from. His father-in-law is an amazing story to read, Daniel Roberdeau who was a merchant as well, and was in charge of a lead mine operation in Western PA during the Revolutionary War. This guy was a patriot to the nines!

"As a member of the Pennsylvania committee of safety he labored indefatigably to improve the defenses of the colony. As an agitator for independence and a new state government and as chairman of the Philadelphia mass meeting on May 20, 1776, he was an important factor in uniting the popular group in the city with the back country, thus paving the way for a new constitution. He interested himself financially in fitting out privateers which were successful in capturing valuable prizes. When bullets were needed for the army he volunteered in Congress to establish a lead mine at his own expense in western Pennsylvania (1778) and built Fort Roberdeau to protect the mine. He also served with the Pennsylvania Associators, first as colonel of the 2nd Battalion, and later as brigadier-general of the 53 Battalions, to which post he was elected on July 4, 1776, and in which capacity he participated in the New Jersey campaign of 1776. Beginning Feburary 5, 1777, Roberdeau sat in Congress for two years."
Notice his interest in outfitting privateers to capture valuable prizes...
"While in that body he served on the important committee of foreign affairs, and with his wide knowledge of business matters rendered valuable assistance in reorganizing the clothier general's, the commissary, and the treasury departments. A foe of inefficiency and dishonesty, he strenuously advocated both in Congress and in his state the strictest economy, adequate provisions for the army, and measures to prevent a depreciated currency, characteristically declaring that "these will be more effectual than an army with Banners". "
This man was involved with the treasury department and preventing a depreciated currency...
