"The book would be a "Treasure" for the "FURCRON Family" it was written for, of which unfortunately, I am not a member."
Sorry I don't mean to pick, but I have to correct this. Two people named Smith may not be cousins as thousands of Smiths came to this country. But as both spellings of the name Fourqurean and Furcron trace back to the same ancestor I can guarantee that you are the same family. It is just a different branch with a different spelling.
The descendants of Jean Forqueran including FOURQUERAN, FOURQUREAN, FURQUERON, FERQUERAN, FIRQUIN, FURCRON, FURKIN and all other variations are one family.
