SEARCHING MY HUSBAND'S MARQUIS ANCESTOR

For many years I have been searching for the answer to who my husband's ggg grandfather was.His surname was Marquis & he married Elizabeth Thompson. He had a son named Jesse Marquis born 20 May 1820 in Pa. Family history states that he died just before Jesse's birth. I don't know where he died or why. Anyone who could help me I would be very grateful. I have Marquis family history from Jesse to current.
