It's a standard legacy address.
And it doesn't matter whose address it is, only with the private key or the seed you can gain access to the funds and you said it's yours then you should have the keys and if not then you can consider the funds is lost forever because there is no way you can find the privatekeys when you have no idea of characters in particular order.
