The (full) OED reference to 'thole' as a noun, where the definition is given as 'Patience, forbearance, endurance' has the observation that it's 'obsolete/rare'.
The reference to 'thole' as a verb is noted as 'now northern dialect or acrchaic'. There are various (overlapping) definitions offered, as follows:
1. to be subjected or exposed to (something evil); to be afflicted with; to have to bear, suffer, endure, undergo.
2. to undergo trial (as in 'to thole an assize').
3. to endure without resistance or complaint; to submit with patience to; to bear with, ‘abide’; to put up with, tolerate.
4. to endure or bear without giving way; to withstand; to stand.
5. to bear, stand, admit of, be capable of; to have room for; (esp. in phrase to thole amends) , to admit of improvement.
6. to allow, suffer, permit.
7. to be patient, have patience, wait patiently.
8. to bear to give; to afford or grant willingly.
I've never heard of it (and I lived 'up north' for 20 years!)
