I am a descendant of the Rathbone family. I was roaming through this file and saw your post from 2010, hoping you still check this forum for information.
Who would the John Rathbone you ask about, be his parents?
In my family I find several with the name John. My first John to show up was born ABT 1755, mar'd to Joanna Joslin. Their Daughter, Isabel was b 1795 d 1829 in Herkimer Co., NY.
Does any of this mean any thing to you? Please respond to my email, firstname.lastname@example.org
if it does. Looking for more Rathbone information, let's compare notes. Thanking you in advance.
