Guillaume de Tancarville, I, Seigneur de Tancarville - Trying to find the time line of my surname

Started by Private User on Sunday, December 30, 2018

I have been searching for how and why my Grantham name started,
I have a Baron William de Tancarville married to a Baroness Matilda d'Arques
Parents of one William Baron of Graeghan Grantham 1.
My question is how and why is he the first Grantham, when his parents weren't?

Dana Grantham Collins
