There was a John Cameron who served as a scout [possibly a spy] for the British , during Rev War , but did not claim military service . His Loyalist Claim is a must read for any possible Cameron relation . I think he was also connected to the KRRNY and Sir John Johnson , but do not recall if he was a tenant . He received Lot 6 Concession 4 in Cornwall Twp. Stormont County . There is a family Cemetery still located on that lot . Your William Cameron might be buried there . I think a Mr John Bulloch might be trying to catalogue who is buried in this said Cameron Cemetery . He sometimes views this site so maybe he will reply .
