Lislarris and some adjacent townlands were sold by order of the Encumbered Estates Court in 1858. (This dealt with selling off the assets of landlords who were effectively bankrupt). There is a copy of the sale brochure in PRONI under ref D1201/32:
14 January 1858 Irish Encumbered Estates Court Rentals. Rental and particulars of the estate of the said parties. Maps of the estate,
surveyed by John Irwine, Whitty.

Fermanagh.
Griffiths Valuation for 1862 lists 2 Scarlett households. Plot 2a was John Scarlett senior with 42 acres. He had sublet a labourer’s cottage (plot 2d) to John Scarlett junior (who would normally be his son).

There’s no mention of either of the 2 Williams in Griffiths so either they had died or moved away by 1862.
You can follow through and see when those properties changed occupant using the Valuation Revision books on the PRONI website. That’s often a clue as to when someone died. https://www.nidirect.gov.uk/proni

Note that according to the 1911 census John had 9 children of whom 6 were still alive.
William, John, Florence & Lizzie all signed the Ulster Covenant in 1912, so that tells you their views on Home Rule. You can see their signatures on the Covenant site: https://www.nidirect.gov.uk/services/search-ulster-covenant
William, who married Bessie Keary, in the 1901 census:

The family appears to have been Church of Ireland. Galloon Church of Ireland records start in 1798 and cover baptisms, marriages and burials. If you have not already studied them, you may get more information on the family from that source. There’s a copy in PRONI.
There is a book on the history of Galloon parish, but for the life of me I can’t remember it’s exact name and author. It’s something like “Meeting at something Cross.” It goes into great detail about some of the families in the area. You might want to search for that. Enniskillen library probably has a copy.
