I am learning more about this as I go.  It is the Blockchain Wallet we are trying to access for which we think we know what the correct e-mail is or at least a new one he set up, but can't seem to determine what the password is on that.  He doesn't know what the seed phrase is and doesn't remember getting one.  We do have a # code for wallet, but not sure if this is for his new account to try to import the old one, but without a seed phrase it seems it will be a next to impossible task.

Thanks for any help or guidance you can give.

Thank you for responding;

This is the only email he can get in to;
allisonronaldg@gmail.com , whether he used it for Bitcoin, he doesn't know. We have the password for this one.

There are others which we cannot get into, no matter how hard we tried, they just send us in circles:

ronaldaallison@gmail.com
ron.allison@live.com  - (the oldest one he can remember)
allisonronaldg@gmail.com  - this one is working, but don't know if it was used with Bitcoin or not.

Seed phrase, and wallet file, he did have, but doesn't know or have them now.

By Bitcoin account, I mean, anyway for him to get back into wherever, and whatever he needs to do, to retrieve his currency.

Thanks hosseinimr93 and Stalker22

My name is Peter and I am a computer tech trying to help my customer, Ron, get back into his account, after his computer died and he purchased a new one.
Unfortunately, I do not know Bitcoin, nor use it, and Ron is not too techie!
He's pretty sure he has the pertinent info, and if he has it, we don't know how to use it to try.

If someone could help and please email Ron or myself, it would be greatly appreciated.

Thank you very much...
Peter
