Venus Williams joined sister Serena in the third round of the French Open for the first time since 2010.
Venus followed Serena onto Court Suzanne Lenglen after the world number one had beaten Teliana Pereira 6-2 6-1 and more than matched her.
Her scoreline against Louisa Chirico was the same but Venus was 12 minutes quicker, defeating her fellow American in just 54 minutes.
Venus has not had quite the same level of success this year so far as she did in a terrific 2015 season but she is setting her sights high.
The American turns 36 next month, and she said: "It feels like I want to keep going. At this stage in my life, in my career, it's like you don't want to lose early, but if it's not the (tournament) win, it's still a loss."
Venus, meanwhile, revealed she considers her four Olympic gold medals to be more important than her seven grand slam singles titles.
"For me, personally, yes," she said. "The proudest moment for me when they do the on-court announcements are the Olympic results. For me, that feels legitimate."
Eighth seed Timea Bacsinszky won the stand-out women's match of the day 6-4 6-4 against Eugenie Bouchard.
It was a topsy-turvy clash with Bouchard showing some encouraging form to win four of the first five games only to then lose the next 10.
From 5-0 in the second set, Bacsinszky, a semi-finalist 12 months ago, was on the verge of seeing her advantage wiped out but held on for her first victory on Court Philippe Chatrier.
The Swiss said: " I was down 3-0, but I was not really concerned. Because she was not head and shoulders above me. It was just a matter of adaptation.
"She was down 5-0, and she managed to play lights out, and he r balls were deep and I missed some shots.
"At 5-4 in the second set, 15-40 on my serve, I thought it could be complicated, but I believed in my abilities. I know that I'm a fighter, and I knew that I would have found the solution.
"Even if I had lost the second set, I would have found a solution in the third set."
Bouchard struggled so badly with the pressure of being the women's tour's hottest property last season that it led to an eating disorder but she is taking tentative steps forward again.
The 22-year-old Canadian said: "It's very disappointing. What's the most disappointing is my game feels good. I feel good on the court. So that's what hurts the most.
"It's unacceptable really to lose 10 games in a row in a match.
"I feel like I made up for it a little bit at least coming back and fighting until the end. I'm always going to do that. So I saved face a little bit. I wish I had had that mentality earlier in the match and not four points away from losing."
There was drama late in the evening when French number three Alize Cornet defeated Tatjana Maria of Germany 6-3 6-7 (5/7) 6-4 despite cramping early in the decider.
Cornet's hopes looked to be over as she was helped back to her chair in tears but she recovered sufficiently after an injury time-out to book a third-round clash with Venus Williams.
Players are not allowed to take an injury time-out for cramp but Cornet received treatment to her other leg. Maria was clearly furious and they exchanged words at the end before the German angrily pointed her finger at her opponent.
It is unlikely to be a friendly contest when the pair face off again in doubles on Friday.
Former champion Ana Ivanovic moved into round three with a 7-5 6-1 victory over Kurumi Nara and then declined to answer questions on her wedding to Manchester United midfielder Bastian Schweinsteiger, which is rumoured to be taking place after this tournament.
