Can someone from the USA suggest how to access the actual record for the following from www.genealogy.com

I had a friend look this reference up for me:

"William Qualtrough: (Historical Records): Reference was to "Genealogical Records, New York, 1675-1920". I was unable to access the actual record as the link was not completed. The information given was as follows: Lived in Castletown, Province of New York, 1775. Source: American Archives (Series), 1774-1777. Publisher: Peter Force, Washington, DC, p. 1142."

My friend also stated that :

" 'Castletown' probably refers to Castleton, located in Richmond County. Richmond County is also the county for Staten Island and was formed in 1683, so it has a very long heritage (for this country).

Any suggestions or assistance as to where to go to get to the actual record for more detail (I hope) would be most appreciated.

Thanks
