I have seen the gravesites of James Whitney and Ruth in Harmar Village, now I believe within the municipal limits of Marietta, OH. James is shown on the head stone as born in Princess Ann, MD 7/22/1771, and dying on 11/13/1852. Ruth Whitney, shown as "consort" of James, is shown as dying 6/17/1832, age 50. Sarah, "daughter of James and Ruth Whitney" is shown as the wife or widow (my note only shows "w") of Ben W. Herr. Her birth and death dates are unfortunately garbled in my notes. Rebecca Bowen is also shown as buried on the site, shown as the wife of James Whitney, born 5/7/1787 in Hartford, CT and dying 9/10/1866. In the "History of Washington County, Ohio 1788-1891", there are many references to this Whitney family, especially to James, who was first mayor of Harmar, later postmaster,a prominent builder of ships at Marietta before the Embargo Acts stopped commerce and shipbuilding. The Whitney house in Historic Harmar Village is very lovely to this day. The History refers to James Whitney as "master builder" for Charles Greene & Company (p. 376), and also refers to the firm of "Whitney & Sharp" as shipbuilders (p. 378). Page 552 refers to the marriage of Rebecca Bowen born 1787 to James Whitney of Harmar, and page 567 refers to the marriage of Ruth Grene, daughter and seventh child of John and Mary Greene, to James Whitney of Harmar. From either the same History or some other reference book I noted the marriage of Sarah Whitney of Marietta to Rev. William Herr on 21 Sept 1830. The History refers to other Whitneys in the area, including Jonathan Whitney, and a Nancy Whitney, daughter of Josiah Whitney. If I come across anything else, I'll write again. I'll certainly be interested in your ongoing research efforts. Good Luck!
