My great grandmother was married to John Marshall Alley! I have a lot of info on the Scovell family I would gladly share with you. As a small child, we lived just across the river from Kendall Scovell but never knew he was related. In fact there was once a very old cemetary across from the old Aldervale cheese factory around the Nehalem area and I was told this was the Scovell family cemetary. I think there is/was a home built near that by a Scovell family member. I can remember Richard Scovell living in that area. Amazing I just stumbled across this after trying to locate the John Marshall Alley manuscript I submitted to the Civil War historians several years ago.
