I can't help with your actual query, I'm afraid, but I'll just butt in and say I have some Scruttons in my tree. They're usually called Jeremiah and seem to be from around the Falkenham area throughout the 18th century, leaving for London in the 1830s.
I've not got a great deal on them - another researcher sent me a basic outline of my line of Scruttons, but not much flesh on the bones.
I noticed on the genfair/Felixstowe FHS website that they have some parish register transcriptions available for this area, so I've ordered them to try to flesh out this branch of my tree.
