You need to request the information from the Social Security Administraion office. The office has it all in their records to forward to you for a small fee with respect to depth of your request. You must request a form entitled "Request for Earnings Information" from them. Go online or phone your local social security office and ask for help to get the form. When you get the form, make four copies and fill one form in its entirety with one social security number and then another with second number. Mail each separately.
