The English player thrilled home fans during the final round of the Ricoh Women's British Open, as she outdueled Pornanong Phatlum at Royal Lytham and St. Annes for her maiden win.
Ahead of a tournament in Abu Dhabi a year ago, Hall hit a drive of 579 yards on Yas Marina race track, believed to be the world's longest drive by a female golfer.
His daughter was born during the 1996 Masters won by English golfer Nick Faldo at Augusta, Georgia, and she was named as a tribute to that victory.
It's given her a great chance of winning a first major title, and claiming a first victory on the LPGA Tour.
Georgia Hall has earned £530,000 from her golf career, according to the Ladies European Tour data.
With her win, she becomes the fourth Englishwoman to win the Championship and first since Karen Stupples in 2004.
"I don't know what it is but the bigger the competition the more enjoyable and fun it is", added Hall when asked about her capacity to play big events such as this event past year and the Solheim Cup well.
Hall, who had held her nerve throughout the back nine, negotiated a bogey at the last to go with her previous six birdies on the day, having held a three-shot lead.
Home favorite Georgia Hall (68) was in the tie for second place along with, who was leading by two strokes on 11 under when she lost her ball in a gorse bush at No. 17 and wound up with a double-bogey 6.
Both players birdied the par-5 15th after Hall's eagle attempt from 15ft caught the edge of the hole and stayed out, but it did not take long for Hall to get her nose in front thanks to another birdie on the next.More news: Facebook removes conspiracy monger Alex Jones for hate, bullying
Phatlum shot a final-round 70 but was no match for Hall down the stretch. "I'm so happy she won".
"I was very confident going into this event from past year (equal third) and I love links golf and I'm playing in England, which is very rare".
For Phatlum it has been an unbelievable week having missed six of her previous seven cuts in this event.
"I just got a huge knot in my throat and I just had to put my head down", he said after closing with a 1-under 69 for his first World Golf Championship title. "It was my goal when I was nine to win the British Open".
So Yeon Ryu fell victim to Lytham's fairway pot bunkers early in her round.
Thomas had not had a score better than 67, and he had not finished higher than a tie for 28th in his two previous appearances at Firestone.
Australia's Minjee Lee was very much in the firing line for much of the week but a final round of 75 saw her eventually finish in a share of 10th place.
"I was loving it, deep down, hitting the shots under pressure", said Hall, who barely showed any emotion all round. His one-under-par 69 more than enough to clinch his ninth PGA Tour title - his first in a WGC event.
Thomas started the final round with a three-shot cushion and was never seriously challenged.
