Hi Sharon,
Did you know you posted on the
Ferry Co., Washington Message Board?
I did find his Social Security Death Index record but it's the same info that you had posted.
The last Census that is viewable by the public was the 1930 Census. After 1930 it is much more difficult to find info about people.
You might have better luck if you post on the
Georgia,
Missouri and
Florida Message Boards. If you know which county he was in for each state, post on those Message Boards.
Also you can post on the
Ferry Surname Message Board. If one doesn't exist for
Ferry, ask RootsWeb to create one for you. Successful Searching!
