There was a family from Cornwall who moved to Laxey, following the mining, called Pearce but transcribed as Perce in 1881.

Richard Pearce 33 Cornwall Blacksmith
Jane ( Richards) 35
Theriza 12 Lonan
William James 10 Lonan
Susannah 8 Lonan
Richard H. 5 Lonan
Emily B. 2 Lonan

By 1901 a James 28 from Lonan was living in Patrick as a Blacksmith at the Mines.
Could this be William James with his age changing slowly?
Both the parents died in Laxey.
