If you post the names and dates, I will take a look for you, in the Burial Indexes.
(I live on the Isle of Man

)
The Isle of Man has a separate jurisdiction from either England/Wales or Scotland.
So there are different databases to look up - not all of which are online.
Isle of Man probate is usually searched at The Registeries - a copy of a will is £2.50.
The Registeries are at the end of my road - so a short walk for me!
