These dates are much too recent for my records. I would suggest you send for the death certificates for both and see if there is any birth info on them. If you can get them back before 1920 then you can start a census search and find the family. At the moment the most recent census that has been opened to the public is the 1920 census. You should have little trouble finding them in it if you have a general location and with luck the father's names.
