Subject: William de Grandison husband of Sybil de Tregoz (who are his parents?)
Date: Sun, 19 Feb 2012 07:43:39 -0800 (PST)


While trying to verify who William de Grandison parents were, I keep
coming across that they were Pierre I de Grandson and Agnès von
Neuenburg, but the chronology appears not to fit.

Leo's great website also provides this linkage:

While looking through the archives I came across John P. Ravilious
post on 8 Nov 2006;

Pierre d. between 29 Dec 1257 & 15 Jul 1259 per ES XI:153 & ES XV:7.
William d. 27 Jun 1335 per CP VI:62, ES XI:154, Turton, Watney 460 &
973.

How likely is it that a son would outlive his father 76-78 years in
the 1200-1300's? Per ES, William also outlived his brothers by 35 to
53 years (see http://genealogy.euweb.cz/french/grandson2.html). Not
impossible, but surely a red flag that it is highly probable that
there is a generation missing between William & Pierre.

Unless my assumptions are incorrect. Has anyone discovered anything
different?
