Maud de Bohun married Henry D'Oyly when he was between 34 to 49 years older than her? Hmm...
I find zero evidence to support either "1109 or 1094" as birth years for Henry.
Medlands does not guesstimate the birth years for Henry or his parents:

Wikitree does not assign the sources included to any datum on ifs profile:

...and I don't have access to copyrighted books Wikitree cites.
Yes, such a big age differential in marriage isn't impossible, but for me, it's implausible. Any thoughts, Erica Howton ?
