Through the probate of Jonah Guthrie's will, I have solid connections between his siblings on this list. In most cases, spouses, children, and location were mentioned. The only tentative connection is to his brother Joel. There is no mention of him in the will as he died relatively young, but Joel's gavestone (d. 1827) is the exact same design as Jonah's 1st wife, Lydia(2) (d. 1826), in the same small cemetery—at various times called the Red Schoolhouse, Creamery Road, or North Bergen Cemetery. Many of the stones have been decimated by snowmobilers so there's no sign of Jonah, who I suspect is also buried there. Joel's marker mentions his parents, Daniel and Lydia(1) Guthrie. I haven't been able to find any other information on them at this point.

So basically, Daniel, Lydia(1), and Joel have a known connection via Joel's stone. All of the others are interconnected through Jonah's will. Joel and parents are then tentatively connected to Jonah through Joel's marker location and design.
