I may be incorrect but I thought I had seen on one of the lists, or even in a SSDI that I found that someone explained to me that the "A" on the end of the Social Security Number meant that they claimed the Social Security as a dependent or a spouse but not under their own number. That brings up your question as to Richard (Male) Kraus' spouse was Frank Unknown. Is Richard male, claiming social security benefits under Frank's number? Kathy
