Guillame III du Plessis, Seigneur du Plessis, des Breux et de La Vervolière - Alternative Data After Merges

On the one hand, the dates we have for his kids in the About (from a link that is now no longer viewable http://johann.grobler.myweb.absamail.co.za/pafg99.htm#1687) appear to disprove the the 1373 option:
M i Pierre du Plessis was born before 1373. He died .
M ii Sauvage du Plessis was born in 1388. He died .
M iii Jean du Plessis was born about 1390. He died .
F iv Jeanne du Plessis was born about 1393 in France. She died .
F v Catharine du Plessis was born about 1395 in France. She died .

On the other hand, the date given for Sauvage du Plessis birthdate - 1388. is actually the date of his wedding - according to http://de.wikipedia.org/wiki/Le_Plessis-.
- which tends to make the birthdates ranging to 1395 look like thumbsucks based on an erroneous assumption about Savauge's birthdate.

Given that, I am going to revert to the c 1373 death date, and ask Angela Joan Wasyliszyn for her sources that are so specific about the 20 April bit - as a very useful point to add to the About.

I am also going to remove from the About, the text on the children's birthdates that appears to be largely thumbsuck :-)
