Looking for Seats of Pennsylvania

These are my great grandparents and I do not have much information on them. Please let me know if you run into any information on the Seats family. I would like to share whatever I can find with my grandmother. We recently revisited her old family homeplace but the owners had the property posted and she would really like to track down any new photos or information on her family or property where they lived to show us grandkids. Thank you.
