Can anyone help with this Welsh place name? It looks like Tegrdar, but I can find no such name.

The beginning could/should be Ty (mutated to T')  yr d.... or cha...  Can't think of a Teyr....

Could you give details of the extract, please. It might help working it out.

Added - are you sure it's in Denbighshire - have been through a long list and can't see anything like it

Many thanks for your help. Teyrdan is probable right, I read the y as a g, There was a Teyrdan hall in the same area that is now a pig farm, so perhaps my ancestor was a coachman for the family that owned the original hall.
