Hi Rachel: This one has me baffled, will add it to my genealogy brick walls. LOL I have gone over the census until I don't know where to look any more. I went to the index and the only Henry H Ross that was born in 1800 is as follows ROSS, Henry H. Other <1800> M W NJ NY( born NJ) (census NY) ROSS, Henry Self <1805> M W PA MO (born PA) (census MO) Henry H is living with a James McGarvey, his wife, Mary and their Son, Joseph. Could this be one of his children that he is living with in New York? I'll keep after this one as there has to be a reason I can't find him. This is a long shot but could he be using any other name. I know I was looking all over for my GGGrandfather and all the time the census had misspelled his name. Sorry, Dee
