CCJ that is not mine.. Help!

Hi all, I’m new to this platform but I’m desperate for advice.

Cutting a long story short.
Recently found out on my credit file (through Experian) that I have 3 CCJs. All of which are genuinely not mine, I’ve never had any type of credit cards, car finance, store card/account, home entertainment such as Virgin media or sky, and so on. I personally have never needed to apply for any of the above. But these ruin my chances of anything financially in the future. Each have a reference number and all held with Northampton county court.

My father and I share the same name and address. I believe this may have something to do with it.

Can anyone advise on the best route to take in regards to finding out where they have come from and hopefully getting them taken off.

Any advice would be appreciated. Thank you
