Looking for my elusive ancestor:John Curtis GREENOUGH b ab't 1794, m about 1812 to Mary [Polly] PRATT. One known child, Elizabeth Ann GREENOUGH b ab't 1812 in upstate New York. Death time/place unknown; possibly by 1830. Does anyone know anything ab't a F.W. GREENOUGH? He was, I think, a lithographic artist or publisher in Philadelphia before 1850. His name frequently occurs when I use a search engine looking for my elusiveJohn Curtis GREENOUGH. Who knows we may be related.Thanks N.
