Alan. There is no Charles Knibbs among the Matching Passenger Records on the Ellis Island website. There are 59 other Knibbs, but no Charles. If John D. thought his father, Charles, was born in Ireland, he could well have thought Charles' parents died on Ellis Island. Remember, John D. was born in 1867. Ellis Island was established late in the 19th century, 1892, I think. Ritchie
