Ephriam Merritt son of Stephen Merritt Capt in Revolution

I am looking for information on Stephen Merritt.From what information handed down to me, he served as a captain during the revolutionary war.He was married to a woman named Mickey. He had a son named Ephriam (1776-1884) who in turn had son named George was born in 1799.George moved to Southern Illinois in 1816. I found court records online regarding a petition for Stephen's military pension but Ephriam is not mentioned as one of his children.Is my information correct?
