How Do I Know Which Email Account Was Connected To My Phone? Locked

Hey All

I Got Locked Out Of My Phone Because My Nephews Made *Too Many Pattern Attempts*

They're Asking Me To Unlock With My Google Account.

I Know The Email ID I Have Used, And I Know The Password.

Works Fine When I Log In From My Laptop

But It Isn't Connecting On My Phone !

I Checked The Connected Devices On My Account, And It Says There Are None !

I Have No Idea What Email ID Needs To Be Put In My Phone ?!

How Do I Find Out Which Email ID Is It Connected To ?

It's A Samsung GT-S5302
