Well, I found some information that I thought you might find interesting.
First, I finally confirmed my own connection to the Barber line that you are connected to. (It turned out that my grandfather's information that I had been given was incorrect, and I found the correct lineage.)
It turns out that your Benjamin Barber (husband of Selissa Sayles) is the brother of my 3rd great-grandfather, Thomas Barber. I'm descended through his son Israel, Israel's son Israel, and then that Israel's son, Joseph.

The interesting bit of information, (that you might have already come across) is that our common great-grandfather Moses Barber was married to Susannah West, (our common great-grandmother) and SHE was the granddaughter of Mayflower passenger George Soule. (Also a signer of the Mayflower compact.) Susannah's mother was George's daughter. (Also named Susannah.)
So Mayflower passenger George Soule is a common great-grandfather that we share!
On another interesting note, other descendants of George Soule include Dick Van Dyke, Richard Gere, and Julia Child. (So we have some celebrity cousins.) :-)
