I have to ask a question. If you owned this stock for years, why have you not questioned why you have not received the dividend checks? I could understand if a relative owned the stock, died, and was not directly inherited by someone their could be confusion, but to own it, and not receive the dividends for years, I have to question this. Are you sure you did not sell it, or possibly anything under 100 shares were paid out in cash to the original owner at the time of the merger. Some buy outs/mergers pay cash for small number of shares owned by investors rather than have paperwork incurred by the new company for small stock positions. Since it was years ago, it is possible you received a check at the merger closing for the shares, and since you did not "personally sell it", you have simply forgotten the payout. Just a thought.
