This looks to be the family you are interested in, in the 1901 & 1911 censuses:
William had remarried in 1895 to Eliza Faloon of Drumhirk.
They had 1 child – Mary Martha born 23.3.1896 at Camlymacullagh.
A couple of Probate abstracts from the PRONI wills site, of a family from the townland. Presumably relatives:
Probate of the Will of John Falloon late of Camly M'Cullough County Armagh Farmer who died 3 December 1899 granted at Armagh to Elizabeth Fallon Widow.
The above will is on-line on the PRONI site.
Falloon Samuel of Camly (Macullagh) Newtownhamilton P.O. county Armagh farmer died 31 January 1941 Probate Belfast 15 May to Essie Falloon the widow. Effects £456 16s. 5d.
