This is a transcription of the birth record for Olliv Hall Dunbar, Vital Town Records of Chatham,
Massachusetts, 3:13.

"Susanna Daughter to Benjamin E. Dunbar & Rhoda His
Wife Born in Chatham March 13th AD 1817. Hannah Their Daughter Born August
28th 1821. Olliv Hall Their Daughter Born June 10th 1823. Lucy Snow Their
Daughter Born in Chatham Sept. 25th 1827."

Another document:

Estate of Gershom Hall, Barnstable Co., Massachusetts. Teri’s copy of this
is quite faint so probably would not scan well, but here is the pertinent
clause: "To Rhoda Dunbar the widow of Benjamin Dunbar the Sum of fifty
dollars." Will was proved Jan 14, 1845.
