This smacks of boasting, but "
pour encourager les autres":cir 1550 on one line that I have researched myself and therefore pretty convincing as far as I am concerned.
cir 1560 on my husband's paternal line, researched by someone else, but so far it all seems to fit together very well.
cir 1100 on my paternal grandmother's line, but only because it links to several armigerous Sussex families who are well documented.
Others are resolutely stuck in the 18th century!
So keep going everyone! They are all interesting in their own way.
