possibly this is unrelated but another query re marriage of a Dr John Theophilus Jones to a Mrs Eleanor Galliard (nee Reeves) 30 Sept 1858 Kk Braddan (his father given as dissenting minister) In 1861 J T Jones aged 34 born Wales,

Now your John Jones was also married to a daughter of Buckle Reeves (Elza G.) and in 1881 they were still in Castletown with his sister Mary (unmarried born Wales) + a Richard E Jones (boarder age 26 born England)
In 1861 census index a Elizabeth H Jones age 85 shown living with John and Eliza

are these Joneses all related ?
