We have been trying to help you, but there is not going to be a quick and easy answer.
So - you have two Thomas, born in the same place in the same year. One with parents John and Ruth, and one with parents John and Mary.
A Thomas with father John marries in 1860, and that is "your" one.
So - can you find what happened to the "other" one? Can you follow the two Thomases, through censuses, finding a marriage for the "other" one etc etc, up to two deaths? Hopefully something along the way might help rule one or the other in or out as being yours. It might mean thinking outside the box, e.g following up witnesses as we were trying to do with the Hannah. So you may want to try and find what other christenings there were for John and Mary and for John and Ruth, and see if following either group of siblings brings any clarity.
I've a feeling it will be a long hard road, but hopefully you may sort it eventually.
No-one ever said Family History was easy! Well, actually that's not true, a lot of people may say it is easy, but they are wrong!!!
