bankruptcy and very old credits that are not on crdit report?

I have several very old credit card debts from the late 1990s that are too old to be on my credit report and ones that are on it too. I want to file bankruptcy and I dont even know what credit cards they were? My ex husband kept all the cards and bill from then as they were in my name but I had no why to pay the, he will not tell me who they were with only that he made me sign for them and racked them all up and then left me.
so how can I declare them for bankruptcy if I have no idea what banks they were with?
He just made me sign for purchases, bilsl, etc and threaten me if I refused. But they were in my name only. I never worked so he filled out all the appliations and then just made me sign them
Now I am half owner in a house and our only income is our social security checks.
What can I do not to lose my house? it is cheaper than renting.
These old credit cards have not ben paid on because I never worked and my health was bad.
