A couple of things - sorry I have not been watching the Board properly. The cutting is probably from the Manx Wesleyan Church Record which became the Manx Methodist Church Record in 1932. THere is a run of bound vols. in MNH LIbrary in the stack.

Also don't forget if someone is mentioned in a will, but without any mention of where they lived - there are four possibilities if they were also of the next of kin. Two of these hints relate to items which would be filmed on the microfilm, but one might be missed on a transcript. The third hint is a separate record, very awkward to get at, but with a couple of possible substitutes;
1. There were sometimes summons slips sent to or received back from parish sumners, notifying people to appear at the probate court. This may reveal a parish.
2. Lists of the next of kin in the probate papers. Quite often these are written - often in pencil or a different hand, on the back sheet of the will, running the wrong way up and down the page. Imagine a will folded once from double foolscap size into a sort of newspaper shape, then over twice more to the quarter foolscap, then the list written on the outside cover of the document, with the name of the deceased at the top.
3. After 1884 there are minute books of the High Court of Justice probate sessions. The Deemster or judge scribbled down notes on who and what the next of kin were. These remain the personal property of the Deemsters, are not microfilmed and only to be looked at by permission. However the newspapers often published these bits of info. and they were picked up by Edmund Goodwin to find their way into the Goodwin scrapbooks which are microfilmed.
4. After about 1900 the whole thing became more organised and you get affidavits as to the next of kin.
