I discovered a book which I believe is stored in the French Archives:
called the Life of Abbey Francois Xavier La France of Memracook:...with an introduction by Abbey Francois Xavier Cormier:......
I cannot actually access the full information about the book: but I do know Abbe LaFrance was in Memracook in 1854
Whats intersting about this book is how many references there are about SIRRE.......various ones: Jean, Pierres,
And whats further interesting is that he spelled it this way: the original way......which must be some indication that the Cyrs closer to the original homeland were still spelling this name this way two hundred years after Pierre......
but the spelling changed as the geography changed.
It would be fascinating to see what is said about our group in this book: and further hilights the fact that sooner or later some of this searching has to be done on French soil.
I know that in certain early pre 1755 French military pay records: both Sire lines are referenced: the Louis and the Pierre.......and we can tell this difference.even though most ofthe first names are the same
because at least one of them was listed as LESIRE and the other as SIRE
What we dont know: is if this spelling was original to the document or later inserted by others in the future who were transcribing it.
We should shortly have the DNA results of a Louis Le Sire descendent to know how or if the Louis lineage fits into our tree.
Le Sire is easily found in Flanders and Picardy.
Sirre is more challenging: one sees it as DE SIRRE.....as the Seigneurs of Gougnie/Gougny in Belgium
occasionally as Le Sirre in and around Paris and northern France
and of course a few times in La Rochelle (which can be tracked to the Andre Suire lines)
and Sirre in Toulouse: which we know should be De Sire with the accent on the end to sound like Searey
Sirre in Northern France: as in the town: also should be with an accent: Sirray.......
but we have to remember accents were never used in French grammar prior to about 1800: so its nearly impossible to guess what sound it should really be
but there is paltry evidence that anyway in France or nearby where the name didnt have that AY or EE sound on the end.
The only cases where it did not were German and English versions: yet we can be pretty satisfied Pierre had a French or near French origin via other clues
What this tells us: if he himself said his own last name without the accent: is that he had strong ties to British influences.
That is very consistent with the whole north eastern French coast......from Rouen to Dunkirk
Its consistent with Huguenot families in England as well: (who were primarily Le Sueurs: who spelled it Sirre)
Even though we find this spelling in Avignon and Provence over to Toulouse: we know enough of the history there and the DNA and the actual name: to be fairly comfortable thats not Pierres immediate family source.....
One other factor is we cant find evidence that any of the French military ships: which were pretty few in number: that sailed to Acadia came out of the Med Sea....although it was a substantial naval area in later years than Pierre
Again: its a matter of tracking the French Military archives of those years in France itself.........they ship records for the most part are highly detailed......La Rochelle being one solid example: keeping track of every ship in and out......
Its going to take boots on the ground in France to really get into the meat of where Pierre came from.
