Don't confuse a deer's territory with it's home range. A does territory is about 80-120 acres and a bucks territory is about 300-500 acres (depending upon terrain and food supply) but it's home range can be vastly larger and will over lap other deer's territory. As long as they are not caught in another deer territory a deer will trespass like a Hmong refugee.
That doe and 2 fawns you're seeing are the territorial owners of the property you hunt on and any others you see are deer outside of their territory but still in their home range. My property has a resident doe who last season ran around with a pair of fawns like you've seen on your land. This summer I saw her with a set of triplets and last year's fawns still following mama. It looked silly watching the six of them walk along and you could tell it was getting old with her. By the fall I'm betting she will have ran off her older fawns. Despite all that I saw and photo'd on a trail camera at least 12 different does and 5 bucks using the same property. If she saw them she'd drive them off but if she was nowhere to be seen they acted like they owned the place. I'm willing to bet that I'm only seeing maybe half the deer that actually use my property and another twice that may pass through once and never come back again.
So don't worry about seing the same deer again and again. Lots more are there.
