My Wetherbee grandmother's line traces back to Oliver Wetherbee who was born in Pepperell, Middlesex, MA in 1774. He married Sarah Stone who was b. in Ashby, Middlesex, MA in 1773. Olver and Sarah married at Townsend, Middlesex, MA in 1793.
I'm trying to see if any of my MA Wetherbees connect to the ones you have in MA. Oliver's grandfather, David Wetherbee, Jr. was b. at Stow, Middlesex, MA and he married Agness. David's father, also a David, was b 1685 at Stow, Middlesex, MA. He married Mercy Brown in Stow, MA, about 1714. David's father was John Wetherbee, b England, married Lydia Moore at Stow, MA in 1684. John and Lydia both died in MA.
Do you see any connection here with your Massachusetts Wetherbee line?
