The Canaries have now found the target eight times in their previous two matches, with skipper Brady Hickey leading by example with four goals.
Barwell boss Ginnelly felt happy with the overall performance, but also highlighted the importance of withstanding Corby's early pressure without conceding.
He said: "I'm over the moon to get three points because everybody knows Corby are flying at the moment.
"We defended well during their twenty minute onslaught at the start, and eventually found a foothold in the match.
"It was a world-class goal by Brady Hickey to put us in front. Class finishing at important times proved to be the difference between the two sides.
"That goal from Brady reminds me of something George Best would do all those years ago!"
Despite not scoring against the Steelman, frontmen Callum Ball and Luke Barlone received praise from the manager, who believes his side has players all over the pitch with the ability to score goals.
"We do have a goal threat from six or seven different players," Ginnelly admitted.
"The two strikers are working their socks off up front, which creates a lot of chances for those around them.
"Pearson Mwanyongo has been a good addition. He's obviously helped us because he's got skill, flair and looks dangerous when running with the ball.
"We've also got Brady, who is standing out a mile".
