Hulbert is spelled both ways urt and ert and sometimes Hurlbert. Two brothers are buried in the N.Spencer cemetery, stones are one behind the other and William spelled his with ert and his brother Luther spelled it urt. I Have been researching the Hulbert family for quite some time and have found no connection between E. Burritt and William and Luther. They also had two other brothers, John who moved to MI and Nathan that I can't locate a death or burial for. Nancy Hulbert Pakkala
