Hi again Lisa

You might not be aware that in many Suffolk villages, the main road is known as simply 'The Street'. In Trimley, that road does still exist but is now called 'High Road'. Also the house called The Limes is still there, and so are the Three Mariners Inn, The Rectory (now The Old Rectory) and Church Lane.
I've had a quick look at some census images, and I think Cabbage Square must have been down one of the lanes running off The Street (High Road), probably on the Three Mariners side around Keeper's Lane. The Felixstowe people will know more, I've no doubt - I only lived around there for 18 years

Enjoy your visit, and let us know how you get on

Carol
