Alfred William Tongue born 14 July 1927, Douglas, died 29 Oct 1976, father Alfred William Tongue, mother Effie Duggan (see IGI).
There is an Effie Duggan born 12 Aug 1894, Ramsey, parents James Cleator Duggan & Esther Quine (see Brian Lawsons site).
There is a James Cleator Duggan born 24 Aug 1863, christened 6 Sept 1863, Rushen, parents William Duggan & Elizabeth Hudgeon who married 11 Dec 1862, Rushen (see IGI). Hope this is of some help.
