The HofI was founded in 1830's - basically run by a committe with church (established ie Anglican) connections and run on voluntary lines (ie all support was begged for by sermons etc) as there was no poor rate in the Island until late in 19th C. It was a residential as well as an centre for distrubution of food etc - basically Douglas based.
In late 1880's a poor rate was introduced and parish guardians given a statutory job of looking after the poor - many did this by paying the Strang (it was in the corner of the Ballamona Lunatic asylum grounds) on a per inmate basis though Tynwald gave £250/year - all accounts were kept separate from Asylum accounts (see brief comments in 1911 Macdonald commission which asked re working of poor law) by 1908/1911 the UK had a health insurance and pensions but these were delayed by Gov Raglan until after 1918 on the Island - after this date the need for poor houses went away as old folk were 'paid' to live at home.
One difference was 2 miles ! but set up under very different rules though I suspect in reality both were similar to live in.
Thanks to Mona who beat me to the correct info - must admit I had difficulty finding out much about it from my fairly extensive collection
