On page 257 you will see that John Hor/Horr married Hannah/Anna Atherton...I am trying to find her parents names. She may be related to other Atherton's in this book, but so far I have been unable to make a connection. Are you familiar with these Atherton families?
I'm afraid I'm still swamped with the Atherton's of England and Wales and have had little chance to start my research of Atherton's in USA - though I do have a number of links from those families who I have managed to find ships passage details.
I'm more than happy to add your Atherton's to my website if you can provide details - it would therefore give you more chance of an internet hit?
