This Edward reportedly went with his wife to Oakland, CA with his wife, 
a Doogan lady in 1848 via a covered wagon.

From the Goldrush.doc, that contains a listing of Irish emigrants during the famine years:

Mary, age 21, arrived from Liverpool on the "ADA-Alice" at the Port of NY 
on the 17 Nov., 1848.  [Vol. 3, "The Famine Immigrants", p. 315.]
