my suggestion is
Thos Fargher + Ann Clark(d/o John of Peel) their son Henry + cath Cowley parents of John (the tailor later letter carrier) but there are some queries re bapts + reported ages of henry's children in eg 1841 census

Johns wife Margt dau of Robt Kermod + Elizth Gell
Elizth Gell d/o Christian Shimmin + John Gell

Christian Shimmin of Ballavarkish d/o John s/o Pat s/o John)

several of these have marriage contracts + wills(some summarised on Manxnotebook)

however this is only my suggestion you need check out the names
