That tree (minus the Romans!) was the basis of the Goldie-Taubman family claim to 'royalty' - see www.manxnotebook.com/famhist/families/awm1889/goldie.htm
the line from Ewan is also 'given' in www.manxnotebook.com/mquart/mq29135.htm

you can accept either (and my comments on Illiam Dhone and his activities + behaviour are I think well known - today he would have been put in gaol for various illicit family relationships).

However our banned 'contributor' (who may well have been trying to sell well known information - not unknown amongst American and other entrepreneurs) was not in my opinon even connected to that line.
His line included a Henry Taubman - a mariner married to Esther Cowell sharing a multi occupancy house in Mill Street in 1841 and in 1851 a widower living with his son George a Stonemason - supposedly a close relation to the Goldie taubmans of the Nunnery. This Henry who claimed birth in Rushen in 1851 was confused with a son of Thomas Taubman + Mary Moore- Mary was however buried well before Henry was born - there was it seems a family history that a Moore was the mother - the Henry would however fit (tho no baptism found)a son of John Taubman + Margt Moore one of whose children was, unusually for a Taubman, baptised in Rushen. It was this I was trying to elucidate - Donna gave I think some part of Esther Cowle's tree and that had a death at the herring fishery so I think Henry was basically a fisherman whose son became a stonemason (again a trade not strongly linked with the Goldie taubmans) one of whose children or grandchildren emigrated towards end of 19th Cend
