My argument for Elizabeth Cockshutt being the wife of William Christian (Illiam Dhone) can be summarised as briefly as I can as follows:
The main sources for Christian family archives are:
* The Christian Annals in the Manx Museum
* A genealogy deposited at the College of Arms, London in 1798, and
* A legalised Pedigree at the Genealogical Office at Dublin Castle, Ireland,
These sources are public but not accessible to an internet searcher. However there is a fairly extensive library of publications produced by historians who have presumably done this research, and I suggest we should be able to rely on these, certainly in preference to other unsourced theories,
The publication I would rely on here is "The Yesterdays behind the Door" by Christian-3293 Susan Hicks Beach (1956 Liverpool University Press). On P. 39 This describes Elizabeth's father George Cockshutt from Kirkham, William and Elizabeth spending her dowry on a house called Nether Sparth near Great Harwood (which still exists) and living there until 1637. All place names are in Lancashire, England.
Some confirmation is provided by a newly digitised parish record from the nearby village of Altham has records for the christening of their sons George and James in 1634/5 and 1637.
I can provide a lot of extra detail if required.
