Thank you for your message and very useful information about my ancester, Thomas Pennington. I have him being born around 1751 and he died (at Barrow Greaves farm) in 1841. I have had a look at Barrow Greaves from google maps and I visited Heysham a few years ago and was aware the land had been used to build a housing estate. I think Thomas Pennington had occupied the Old Hall Inn but am not sure when took up the tennancy. In view of his age when he died in 1841, he must have moved to Barrow Greaves when he was not able to look after himself. The farm was occupied by one of his sons, William and he was the main beneficiary in Thomas's will.
Let me know if there is anything you would like to know about this family. It is a while since i looked at family history but have quite a bit of information to hand.
Kind regards.
