"Richard Kinman, an ancient Friend, who was truly owned and in Unity with his Friends, and of an upright and blameless Life and Conversation, and loved the Truth, and sometimes bore Testimony to it in Meetings.
A little time before he departed this Life, he said, I know my Redeemer liveth, and that he hath done that for me none else can do; and I believe it will be well with me. With which Testimony Friends declared their Unity.
This, though short, is published to shew how this honest ancient Man retained his Integrity, died in the Faith, and obtained a good report. He died the 23d of the Tenth Month 1713, at Bishampton in Worcestershire. Aged 72 Years."
