I found them on the 1920 US census misspelled Chiero,Christophe. Parents on one page and children (Antoinette, Samuel, Francis and Sara misspelled with and "h") are on the next page. Again they list year of emmigration as 1911 for the 3 and the address is 1219 South Marshall.
In a 1915 Philadelphia City Directory they list the street address as 706 Fitzwater.
I have really combed through Ellis Island records in 1911 and cannot find them. The plague that the family has doesnot authenticate their arrival nor list a date.
FAMILY- WE NEED TO TALK TO OUR EXISTING RELATIVES AND TRY TO JOG ANYADDITIONAL MEMORIES.
