Thanks again, Jorose. Maybe Conway's informants did get a bit mixed up with the name of his mother. Emily married an "O'Connell" but does sound like "O'Connor" so maybe ....
I have looked again at son William Henry's baptism in Quebec Canada and was thrilled to notice that one of the 'sponsors' was a William Vernon - more questions to answer now!
As for George's Will - he wrote it in Faouet so I presume that is where his house was. I have also deciphered the name of his housekeeper as Anna Tuell. Here is an excerpt which I transcribed "I bequeath my goods and chattels of which I may be possessed at my death to my daughter Amelia (sic)Williams after payment of the sum of one hundred pounds sterling money of England amounting to two thousand five hundred francs money of France to my housekeeper Anna Tuell residing in my house a sum which is due for wages and for her constant fidelity towards me and my children during the period she has been employed by me eighteen years. I also bequeath to the said Ann Tuell my housekeeper all my effects that is to say all horned cattle, horses, dogs guns and moveable objects that I may possess in France at the time of my death The said sum of two thousand four hundred francs one hundred pounds sterling which I bequeath to my housekeeper Anna Tuell shall be paid to herself or to her order by my testamentary Executors Messieurs Codd (& Co. - my words)Number fourteen Fludyer Street Westminster London ....Therefore by those present I appoint and nominate the said Messieurs Codd (& Co) … agents number fourteen Fludyer Street Westminster London Executors...."
Thanks for the link to the Census - I have looked at 100 pages so far - nothing yet. I have also found the Death Duty Register entries (for George in 1847 and son William Henry in 1869) but at 250 MB download, I will have to wait awhile - I live in a rural area and our internet service is very poor. Your help has been invaluable, Jorose!
