Britain enjoyed two women's triumphs on the second day of Wimbledon as Elena Baltacha outclassed Mona Barthel and Anne Keothavong saw off Naomi Broady.
World number 68 Baltacha, the British number one, overcame her 114th-ranked German opponent 6-2 6-4 and will next play Shuai Peng or Kirsten Flipkens.
British number three Keothavong beat compatriot Naomi Broady 6-2 6-4 to set up a meeting with Petra Kvitova.
But Emily Webley-Smith lost 6-3 5-7 8-6 to Klara Zakopalova.
Heather Watson and Laura Robson both had their first-round matches - against Mathilde Johansson and Angelique Kerber respectively - moved to Wednesday.
And they will hope to follow the example set by Baltacha and Keothavong, who ensured there will be British representation in round two of the women's singles for the first time since 2009.
It also the first time two British women have made it that far in five years.
Making her 10th main-draw appearance at the All England Club, Baltacha secured two early breaks of Barthel's serve to lead 4-0 after 16 minutes on Court 12.
The 27-year-old Scot missed a couple of chances to make further inroads in game five and her opponent then managed to recover one of the breaks for 4-2.
But Baltacha hit straight back and comfortably served out the first set in 33 minutes.
Breaks were exchanged at the start of the second before the Kiev-born right-hander made the decisive strike in game five and got herself in a position to serve for the match at 5-4.
She slipped to 15-40 but saved both break points and a third to win in an hour and 18 minutes.
"I'm very satisfied," said Baltacha, who lost to Petra Martic on the same court in 2010, having been a set and 5-3 in front. "I felt I was playing two players, one Barthel and the other my demons.
"Given it was the same court and everything that went on last year, it's unbelievable to have won.
"I handled my emotions well from the start. I knew I was so much better than last year, in a tennis sense and in the head. I felt like I was in control the whole match.
"Hopefully it will encourage the other British girls that me and Anne are through."
Keothavong and Broady's pairing in the first match on Court 12 guaranteed at least one British woman would advance, and it was Keothavong who prevailed to maintain her 100% record from three meetings with Broady.
"That was a really difficult match to play," stated the 27-year-old, who let slip a 4-0 lead in the deciding set to lose 3-6 6-2 6-4 to Anastasia Rodionova on the same arena in last year's first round.
"It's nice to kind of banish the memories I have of last year. I made it a point of sitting on the other side of the umpire's chair. I had friends and family seated in different places.
"It has been a tough year. I've had some good wins, but some terrible losses. I'm at the stage in my career where I just want to go out there and give it my best.
"This is a life that I'm not going to have forever. I don't know how long I've got in this game. From my point of view I had to go out there as if it was my last Wimbledon.
"There's no guarantee that I'll be back again next year. I just want to know that I've given it everything when I do hang up my racquets. I'll be able to live with that."
Keothavong faced a break point in her first service game but saved that and soon settled into a tidy rhythm.
Her drop shots were causing 6ft 2in Broady, 21, particular problems and the Wimbledon singles debutant faced a break point in game three.
Keothavong was beginning to look increasingly confident and having dominated her opponent's serve for 0-40 in game five, she struck at the first opportunity with a forehand pass up the line.
The double break soon arrived to extend Keothavong's advantage to 5-2 and she saved three break points before serving out the opener.
A winning forehand approach enabled the world number 111 to apply further pressure in game five of the second set and Broady sent a forehand long to hand over the initiative.
Keothavong looked comfortable thereafter and despite squandering a match point at 5-4, she gained two more in game 10 and came through when Broady failed to control a backhand service return.
Meanwhile, Webley-Smith lamented a missed opportunity to progress after her defeat by Zakopalova.
"I'm absolutely gutted to lose," commented the 26-year-old. "She just had that little bit more experience of playing at this level. I loved it out there, I just wish I had another chance tomorrow.
"Next time I'd like to be in the main draw by right without a wildcard. I know I can compete at this level."
British number two Watson, meanwhile, has been scheduled to play Mathilde Johansson first on Court Three and Robson faces Angelique Kerber second on Court 16.
Officials at the All England Club (AELTC) had to re-organise a number of matches after a downpour brought a halt to proceedings on Monday.
Robson's was not given a specific court or time slot on Tuesday's order of play and she had to wait until after 2000 BST before being informed she would not be playing.
"Bit of a shambles this evening," the 17-year-old wrote on social networking site Twitter.
An AELTC spokesman said: "With the rain we have had, it was inevitable that there will be one or two frustrations along the way. The referee has had to alter a lot of games in the overall programme."
