I recently read your posting on Pleasant Sullivan. I am a descendant of Charles and Mary Charlton Sullivan.My records indicate that Charles and Pleasant were brothers, both sons of Owen Sullivan II and wife Mary Margaret Hewlett. I have Pleasant's date of birth as 15 August 1737 and death on 12 March 1840. If that is correct, he would have been 103 when he died.I have his wife's name as Milly Berry, but that is all I have on her.I believe they were married on 1 May 1788 which would have made Pleasant 51 when they married.I also have info that he was married a second time to a Frances Garrett 8 yrs. after his first marriage.
Is this the same Sullivan family you are researching?Would like to hear from you if you have time.
