Don de Xavier ... He passed away in 1720.[1]

I found this on ancestry, posted by mary severe mandgie. Doing some research. It seems that everyone takes the seviers back to Don Juan de Xavier. Okay, but start adding up the dates and you'll see that some of the generations are out of alignment. Don Juan de Jasse, Chief Counselor to John III de'Albret who became King of Navarre when he married Catherine de Foix, married Maria de Xavier, who had inheirited her rank and posistion and castle from her Spanish mother(because of other heirs)-she was very wealthy. Don Juan took her name and rank and castle. This was in the mid 1400's. They had a HUGH family, the last born was in 1506 and became St.Francis Xavier (founder of the Jesuits). The lineage is thru one of his brothers, who was probably named Juan and then his son, and then his son, before it gets to the Don Juan de Xavier born in 1652 .This is the Don Juan de Xavier that has Valentine (John the Huguenot) in 1678, who in 1708 in the Parrish of St. Giles, Crippingate, London, England marries Mary Smith who was also born in that place. Two of the sons born to them, Valentine Sevier and William Sevier (SEVERE) ran away to America about 1740. Valentine went on to settle and have John Sevier in 1745. I am descended from Valentine "Hughuenot" Seiver. Wikitree Chaves-84

Xavier-31 and De Xavier-1 appear to represent the same person because: sane wife and child. De Xavier seems to be original LNAB,but pleade investigate.
