Two acres is not too much ground for a homestead orchard if you vary the trees. Commercial orchards are designed to produce large quantities of uniform fruit. That's not what you want in a homestead orchard. Instead, you want a large variety of fruits from late spring to late fall. Many fruits, like cherries and some pears, are not self-fertile, so you need multiple varieties for pollination.
Apples have a lot of varieties. I love Gravensteins for cooking. They aren't the prettiest apple in the world, but they make great pies and applesauce. The new breeds like Fuji are very popular. You don't see many yellow transparents any more, but they are a very early apple that will give you fresh fruit a month before anything else, but don't keep well. Rome beauties and Jonathans are great winter apples if you have enough cold winter days, as is Granny Smith.
You need bing cherries, royal ann and pie cherries. You need 3 or 4 varieties of plum and Italian prunes. Don't forget figs, if your autumns are warm enough for them to ripen. Apricots. Bosc, comice, Bartlett and Asian pears. For peaches, I recommend sticking with free stone varieties if you want to can them. Paw-paws and persimmons. Don't forget the nut trees, like English walnut and hazelnut. Hazels are male and female, so plant half a dozen females and one or two male pollinators. There are blight resistant chestnuts on the market now, and there are also winter hardy almonds.
