Welcome to OSM, Pommit, and thanks for sharing local knowledge!

I notice you've deleted the beginnings of the Triskelion Way here - https://www.openstreetmap.org/relation/17932947/history - which I'm guessing was just an accident? I had only added the short part I spotted when I last visited the area, so it was still incomplete. At some point I aim to add the complete route in.

Please use caution when using MannGIS for names etc. It's a copyright source, so we shouldn't copy data directly from it. I think it's fine to use to corroborate other sources though, including your own local knowledge.

Also, if adding Manx names, it would be great if you could specify it as the Manx name. When you add a name in the editor, if you press the '+' beside it then choose Manx in the field that appears, and enter the name in there as well.

Feel free to send a message if I can help with anything!
