I have been reading through this thread and I feel your pain.
I have been researching my husband's family for almost 20yrs and his 2x great grandparents were called Hamilton and Taylor who married in 1858 and came from the same areas.
The marriage banns were read in both Draperstown and Ballynascreen.
The Hamilton family definitely lived in Carnamoney
I believe it was his 2 x great grandmother named Taylor who came from Ballynascreen but, her father's name is given as John Taylor, a farmer.
Noticeably, there was no child named John among their children.
Trying to research these families has always been difficult and can find no definitive proof for anything beyond this couple but, have made an informed decision that the parents of his 2x great grand father were Robert Hamilton and Mary Ann Hanna.
If you look at some of the possible connected marriages provided by others on this thread, you will see the name Hanna appearing as witnesses.
My husband has a lot of DNA matches linking to various couples from Draperstown .
It's not clear if their research is correct or if guesswork was involved but, based on their information, I can't make the exact connection to any of these matches but, it's always the same batch of last names that lead to Draperstown. : Hamilton, Taylor and Hanna.
The name Moore appears in children and they also had childrn named Samuel and Matlida.
My husband's 2xgreat grandfather died in Carnamoney in 1877.
His widow and all of their children moved to Scotland.
( none of the possible connected marriages posted refer to their children)
The other thing I noted is although the 1858 marriage states the couple were Presbyterian, after their move to Scotland ( I dont know what faith they practised in Ireland) this family was definitely Christian Brethern
Have you done a DNA test?

EDIT.
After many years of searching, I discovered the death of my husband's 2x great grandmother and found where the name Moore came from
She was the daughter of John Taylor and Eliza Moore and she and all her siblings were born in Moyheeland.
Taylors on the Griffiths Valuation at Moyheeland are John, James Snr, James Junr, Thomas and David.
David Taylor was a witness to the 1858 marriage of my husband's 2x great grandparents.
It's a bit of a guess but, it's more than possible that my husband's 3x great grandfather John Taylor and Thomas Taylor referred to in the OP were brothers.
Perhaps they were the sons of James Taylor Snr
