The walsh brothers began their pro careers on the same bill in 2008
Cromer's Liam Walsh has won the Commonwealth super-featherweight title after beating Maxwell Awuku on points.
The 24-year-old, in just his 10th professional fight, had never gone beyond six rounds before going the distance against the durable Ghanaian.
After a strong start, Awuku tested Walsh severely between rounds six and eight, but Walsh finished powerfully to win with a unanimous decision.
Liam's twin brother Ryan and elder sibling Michael also won their fights.
Trainer Graham Everett was delighted to see such a convincing performance in such a risky fight at York Hall in Bethnal Green on Saturday.
"He had two or three sticky rounds in the middle of the fight, but got back to his game-plan, boxed and moved and gave a masterclass.
"This kid was ranked number 15 in the WBA, you can see where that's going to put Liam now," he said.
Everett said that despite Liam's inexperience, there was never any doubt he'd be able to fight the 12-round championship distance.
"Liam's in the gym seven days a week, the biggest fight I'm going to have now is making Liam Walsh have a complete week off.
"By Wednesday or Thursday I bet he'll be on the phone: 'Please let me come in,' and I don't want to see him for a week," he said.
"Boxing's his life so we took the opportunity and he grabbed it," he added.
25-year-old super-bantamweight Michael Walsh had Ian Bailey on the canvas three time in the first round before the referee stopped it within three minutes.
Featherweight Ryan had a tougher time against James Ancliff, but was a comfortable points winner over eight rounds.
More than 300 fans, affectionately dubbed the 'Farmy Army,' had travelled from Norfolk to cheer on the trio, and Everett praised their efforts.
"They're so important to all of us, they're so noisy it's unbelievable, they sing so much you end up singing with them," he said.
