Military service

While in Connecticut with his family in 1775, Waller joined the Revolutionary army as a private within Captain Hickock's Company, which was part of Colonel Beardsley's Sixteenth Regiment, which was in turn part of the Connecticut Line. In 1779, he participated in the expedition to Farfield and Darbury, Connecticut.^[1] He was also wounded in a military engagement at Horse Neck, close to West Greenwich, in the same year.^[3][1]

Waller eventually attained the rank of captain.^[4] Once the war ended, Waller returned with his family to the Wyoming Valley.^[1]

Later career

After returning to the Wyoming Valley, Waller came to own significant amounts of land in and around Wilkes-Barre. Prior to 1787, he constructed a house on his lower farm. More than a hundred years later, in the early 20th century, it was still standing on what was then Division Street. In the early 19th century, he sold his farm in South Wilkes-Barre and bought the Putman Catlin farm, a large farm on the Susquehanna River in Oquago, New York (now part of Windsor, in Broome County).^[1]

When the state of Pennsylvania was awarded sovereignty of the Wyoming Valley region in December 1782, Waller did not oppose this action. On April 21, 1787, he signed a document supporting the laws of Pennsylvania and in that year, he took an oath of loyalty to that state. In 1795, he was on a jury that conditionally convicted several anti-Pennsylvania conspirators.^[3]

Waller's name appears quite frequently in the earliest records of Luzerne County. In 1792, he, Zebulon Butler, and Timothy Pickering were on a committee appointed by Wilkes-Barre to determine a location for a new Congregational Church. The site they chose was on Wilkes-Barre's public square.^[1] He eventually went on to become a relatively prosperous landowner and was also a farmer.^[3][5]
