I'm looking for - and not finding - information on several early sailing ships that brought English immigrants to New York and Philadelphia from Liverpool. The Manhattan arrived on one voyage in New York on 21 May 1821 with my 3rd great-grandparents Benjamin and Dorothy Ripton/Repton from Derbyshire on board. Dorothy's sister and her husband, Elizabeth and William Burton arrived from Derbyshire in Philadelphia on 3 Jun 1823. In looking through the ships listed on the ShipsList website, I can't find any of this early vintage - there's a Manhattan, for example, but it was built about 1866. Does anyone know of any online source for these early sailing ships? Thanks. Joanne Gaudio
