I see a very straight-forward, old-fashioned documentary vision here. The corn, the purple flowers, the first shot of your grandmother, and to a lesser extent, the one of your grandfather--all these photos are not flashy, not "wow factor" but are an old-fashioned type of quiet eye style of shooting photos. Minimalist, direct, simple, NOT flashy. A photographer who used to epitomize this type of photography was a man, long since dead, named August Sander. He is one of my idols.
As The_Traveler showed however, your photos would benefit from better, more skilled processing techniques, such as dodging and burning, to de-emphasize things that detract from the image, like for example the bowl in front of your grandfather; it was so bright, that **it** had become an important element in the photo, competing for attention. Making the bowl darker made the bowl less important than his face, and improved the image.
