Seeking info on anyone by this or similar name (Jerrard, Gerard, Gerrard, Garrard, etc.) said to have been from Devonshire, born "about 1798" and wound up in USA (northern New York state, possibly via Canada). It is unknown how or when he got across to North America. He may have been in the British Army at some point between his birth and 1820 when he got married and started a family in Jefferson County, New York. He has many descendants her in the US but we know nothing of his origins except what I have posted here.
