ok will ask my cousin in Grenada his mother died last year and she would have told him about the family history. the Grenville part sound like our family as my Grand father used to talk about that place alot.

I do believe if you dig deeper you might find that the McDonald might actually come from the La Granade family as that the name most of my relative used to call my grand father by Mr La Grenade. trying to contact my cousin to see if i can get some certificates over there.
