It's my understanding that sometimes a reputable breeder will use a lead referral site for leads or inquiries only and then the breeder contacts you directly to ask you questions about the home environment and such before they agree to the sale. In many of these cases they are not puppy mill puppies but puppies raised in a home. Ask your Aunt if she spoke to the actual breeder. Regardless you will most likely fall in love immediately. Your vet will tell you if your puppy has come to you healthy and will check for lp and any obvious disorders. Congratulations, relax and enjoy your new little one
