Woo! Finally, I found a copy of his Will online:





It's written in pretty dense Chancery Script and it may be a while before I have to time to sit down and transcribe it but in my quick overview I haven't found any mention of a pyramid, gambling or indeed any above ground internment at all.

The first paragraph seems to be all about looking after his wife:

. I give to my Wife an annuity of three thousand pounds payable during her life and to be enjoyed as her separate property free from the control of any husband whom she may marry whilst said annuity shall ouccure from my estate and shall be paid quarterly without dedution and I request for her to reside with my brother Edward Mackenzie in the house No 74 Grave Street Liverpool or any other house she may wish in where apartments of her own hire and for living shall be allowed to her should she so live to accept this at my decease or at any future time I own that she be allowed any out of my houses within the parliamentary constituencies of Liverpool (excepting that one at No 74 Grove Street) for a residence free of rent and all other charges for the natural term of her life or so long as she may reside in it.
You can see why the 3/4 pages of it are going to be a bugger to transcribe, but I will endevour.
