I want to know the answer to the following question:
During whose reign was the former town of Sutton referred to as Plymouth?
All the background I'm provided with is that "The settlement of Plympton, further up the River Plym than the current Plymouth, was also an early trading port, but the river silted up in the early 11th century and forced the mariners and merchants to settle at the current day Barbican near the river mouth.". Is that enough to answer the question?
Answer: no
