Thanks for the link.
I located the Rochester Republican, Monday, Feb. 12, 1838. Died, At Clyde, Ashtebula, OH, on 2d Feb. inst., of consumption, Mrs. Mary Ann Bush, wife of Roswell Bush, formerly of this city. I believe she is Ann Canfield.
I hope to locate a death notice for a Mr. White between 1839 and 1842.
