all children are baptised in marown not Patrick so looks as tho moved to Foxdale post 1841; can't find them in 1841 census on Island - Cath is I think buried Rus 18481229 as Cath Pierson, Johnathan bur St Marks age 68 1865 (noted as Barrule) - dau Isabella bur age 9 Pat 18510604
Johnathan junr m Margt hastie age 17 in 1860 + had children Agnes + Johnathan? before she d 1862

There is an Irish born Ellinor Person/Pearson with a watterson family in Rushen in 1851 + 1861 the age would fit as a d/o of Cath but can't place as just noted as servant in census
