I am looking for information on the Gilbert and Mary Pratt family of Burlington VT. According to my gg grandmother's death certificate (of June 5, 1890 Leominster MA) she was 47 at death making the year of her birth 1842-43.( My gg grandmother's name was Mary L. Pratt Joslin). It has her birthplace as Burlington Vt. and her parents' names as Gilbert Pratt and Mary Pratt (no maiden name given). The certificate lists both of her parents as being born in Canada. Also, what is the best place to write to get marriage and birth records for Burlington, Chittenton County for the years 1830-60? Should one contact the specific town or the county or the state?
