Actually, from what I have seen in wills and various court records from Lower Norfolk Co., John Martin was both the Adam Keelings's father-in-law and brother-in-law! I know - kind of gross :) John Martin was born around 1616 and was married at least three times. The first wife's name I don't know, some say she was the widow of a man named Watkins, but I think that is just based on the fact that he witnessed some records having to do with Watkins' estate. Anyway, she and John Martin had two children, John and Ann. Ann Martin married Adam Keeling, making John Martin Adam's father-in-law. John Martin's second wife was Grace and she was the widow of a John Dyer. Based on some estate records for Dyer, they married around March 1659 and had one daughter who may have also been named Grace. She married Adam Keeling's brother Alexander. Finally, John Martin married Ann Keeling, the sister of Adam and Alexander. She was much younger than John Martin. They had one son Joel and then John Martin died in 1666. So that is how Adam Keeling and John Martin were both father/son-law and brothers-in-law. It was as his son-in-law that Adam Keeling inherited the land through his wife when John Martin died.
