About Bertrand Dupeiron
Bertrand Dupeiron or Dupeyron, French-born, circa or before 1790.
In 1795 two French armies invaded Spain, .......one of them took 'Bilbao (on 19 July 1795).'
Sometime later his father became the French Consul in Bilbao, Spain. Bertrand's son(s) spent most of the holidays there in the 1820s and 1830s.
It is therefore assumed that Bertrand passed much of his time in Bilbao, Spain.
Married - before 1821 (Felix's birth year) - to a Spanish lady of Belgian/German ancestry, whose last name was " De Brath". The De Brath name can be traced back to the 16th Century in Wallonia, Belgium - a German-speaking part of Belgium - when a De Brath was recruited by the Duke of Alva to form part of the Royal Guard in Spain. The Germanic spelling ending with a 'th' would be correct and the pronunciation would have been "Brat".
[In the case of De Brath, De was always spelled with an upper case D, denoting Spanish upper-class]
Bertrand Dupeiron De Brath is so named by his son's English marriage certificate. Bertrand's wife's last name "De Brath" should have been omitted - to simply read "Bertrand Dupeiron. Bertrand's rank or profession is listed as 'Gentleman'. Perhaps Felix was trying to simplify the Spanish naming laws and simplify them in England, as he continued to show his name as Felix D. De Brath.
According to Stanley De Brath, son of Felix:: the family name was Duperrier De Brath. Felix was sent to a Jesuit College in the South of France to be educated. This could mean anywhere in the southern part of France - but possibly near where the Dupeiron family came from.
Some research has turned up a number of Bertrand Dupeyron (Dupeiron) names from the same family in St. Martin de Noe, Landes, Aquitaine, France - between 1675 and 1732.
The link to this Bertrand Dupeiron (b. circa or before 1790?) has yet to be established.
