2 years in a blink of an eye for this kind of research.
Well do I have a tale for you...
He probably worked for my gggggg... grandfather Timothy Knapp. History now has him recorded as a patriot but he was a Tory spy master. He ran Knapp's Tavern, now owned by the DAR it is called Putnam Cottage and can be googled. They were the ones that changed Tim Knapp from a Tory to a Yankee. The tavern was in down town Old Greenwich but he owned a farm on Round Hill very new the NY border. There were Lockwoods very near that farm. When he was found out they got the names of his couriers. All the Yankee officers stayed or at least ate and drank at his establishment. It was one of the best reputations for taverns between Boston and NYC. Both his father and brother named Israel Knapp were stauch Yankees so the Tavern was approved as safe for Washington and Putnam to stay when they were in Greenwich. Being a border town it was well supplied with soldiers and Generals came there more than most places. Knapp would then give the information to couriers to ride the information across the border. Having the safety committee (the R-War Homeland Security) approved tavern as a spy head quarters was something to be kept a secret. To hang any guilty party would require a trial. The safety committee would become a laughing stock. Instead Timothy was sent to Simsbury mine, a mine that started with a 50 ft vertical shaft. That is where Torys and POWs were kept. The couriers were whipped and told to leave and never show up in Greenwich again which the Knapp boys did not even after the war. Even when their father and mother died. The couriers were mostly teenaged boys that were expert riders. Check the Fairfield CT site it has a great deal of transcribed records. There is a book on Greenwich by S.P. Mead that may have info on your Lockwoods. It is in Googlebooks.
You might also check the McDonnald Papers kept at the Westchester HS for Lockwood.
I believe your Lockwoods married into the Browns, Banks and Knapps. Check probate and land transfers. They are posted on the Greenwich site below. The Greenwich HS has a more complete set of land transfers.
