This is more 1824 to 1835. I take your point about holidays.

The Isle of Man Steam Packet Company (the current ferry company) was founded in 1830.
There were other shipping companies before this, but they were a bit irregular?!
The Isle of Man had a Garrison, at Castle Rushen, Castletown.
Was there any military service?
BTW I went past Tynwald in the I of M last week. I thought it would be on a hilltop which it isn't
What you went past was Tynwald Hill - allegedly built using stones and soil from all 17 island parishes. It is all of 12ft high!
