..there's a happy family history researcher
I recently downloaded the Will of John Stace who died in Buckinghamshire in 1661. He named his father-in-law, his wife and their children, including my hitherto anonymous 9xg-grandfather, Christopher, who was helpfully described as 'recently deceased'. Armed with that info, I found Christopher's burial in London, together with his children's baptisms.
It also allowed me to take John's wife's family back another couple of generations. Her grandfather's Will named his 5 children and 14 grandchildren, and her grandmother's Will (made 5 days after her husband was buried and only two days before she was buried herself) distributed the contents of their house, including 'the bed in which I lye'. Each granddaughter was bequeathed a sheet.
I love it when it all comes together!
