There is a gravestone in Raffrey Presbyterian churchyard to the Crosson family.
Erected by Robert Crosson ‘of Barnamaghery’ ‘in memory of’ his father, mother and two sisters, then he himself is buried there.
It’s not terribly clear to read from the photo, but the dates given are 29 Dec 1896 (father), 1890 (mother), 1873? (sister, unnamed), and sister Eliza 6th Jan 1925? (almost sure this IS 1925).
Robert’s death then given as 15th Jan 1932?
I have found the death registrations for his father (Thomas Crossan), indeed 29th Dec 1896, and his mother (Mary) 29th Dec 1890. (On irishgenealogy.ie).
They lived at Barnamagery, county Down, which comes under Downpatrick registration district.
Robert is at that address in the 1901 and 1911 Census with his wife, and his sister Eliza lives with them, unmarried. Robert was born about 1860, and Eliza about 1847. She applies for the pension in 1917 (from the 1851 Census Extracts, so pesumably she thinks she is 70 then), giving the same address in Barnamaghery.
I have tried all permutations of Crossan - Crossen; Crosson etc but just cannot see a death registration for Eliza or Robert.
I would be very grateful for a second pair of eyes to have a look and see if I’m missing something!
Many thanks
