Grenaby house - in 1881 an Eliz Corrin of the correct age to match the 1911 sighting was an unmarried niece with John McClements (unmarried farmer) - he (as plain Clements) was a son of Cath Clarke with a sister Maria (unusual name for Manx) who m Robt Kewley thus I couldn't find how she was niece - I don't have the 1891 or 1901 censuses but might be worth checking on Elizth who may hold a key to mother - I wonder if she was the Eliz of the correct age bur in Bra in 1925 (again I don't have braddan burials for this period wch may give her address )
