Betsey Pollard, Kingston, NH, 1700-1800

I am lookin for information on a Betsy Pollard, who married Webster Davis. Webster was born July 15, 1751 and died January 1833. I don't have dates or parents for Betsey/Betty/Elizabeth Pollard. They lived in Kingston, Rockingham County, New Hampshire. Any information will be appreciated. Thank you, Susan McAteemcatee1@prodigy.net
