Sadly no mention in the book.

I do have a random snippet of information in my files on Isabel Huddleston alias Alexander who inherited a Dwelling house, out-houses& backside and garden in Douglas from her husband Robert Huddleston d1702. Robert was the son of Thomas d1663 and Jane Murrey d1670. (see Nigel Crowes site)

The Murreys were Merchants (very rich - search for David or John on Manx notebook) and the Huddlestons were a prominent family - a Thomas Huddleston was deputy Governor, again, run a search on manx notebook.

Sorry no book reference, but maybe with a bit of scratching around and some creative thinking you can connect this Alexander to your family?
