The complete trade history of every MtGox customer up to 30.11.2013 was leaked in 2014, you can find your own trade records in the leak. However, the leaked trade records didn't contain emails/names that you can search for, so you need other details to discover what your userID is. This page may be helpful: https://bitcoin.tax/mtgox

If you registered at MTGox before mid-2011 you can use the user database leak from around then to find your userID, which you can then use to search the trade records.
