Peter Wainwright, Sr. of New York, who lived in the early 1800s, had two sons, Peter, Jr. and Jonathan. Peter became a banker in Boston, and Jonathan became a minister in New York. Jonathan married Elisa (Eliza) Mayhew, and they had two children, Elizabeth and Mayhew. Peter married Charlotte Mayhew (perhaps the sister of Elisa).
Correspondence among members of the Wainwright family, ca. 1800-1840; early correspondence of Elisa Mayhew, ca. 1777-1800; other correspondence to members of the Wainwright family from friends and business associates; financial and legal materials of the Wainwright Family, 1804-1837, plus undated writings and notes; and other materials containing correspondence, financial, and legal materials of various people (possibly unassociated with the family), 1804-1893.
