If I am not mistaken there is a website that holds information the transactions, confirmations and respective involved addresses but I don't recall the url.
What I would suggest you to do if you have part of the sff address, is to open up Google and do a query if the two parts of the address surrounded by quotes, like the exanple:
"XXXXX" "YYYYY"
XXXXX would be the first part of the address you know and YYYYY the second one.
This guarantees that Google looks only for pages that contain exactly those parts of information, and that could result in the address you are looking for.
