Emily (Unknown last name with new husband) (nee Waltham and previously Geller) was Rachel's boss' niece who begins dating Ross at the middle of Season 4.

However, the wedding goes sour when Ross accidentally says Rachel's name instead of Emily's when giving his vows. They get married, but, feeling humiliated, she goes into hiding. During Season 5, she makes occasional appearances, until Ross convinces her to go to New York with him. She accepts, but only on the condition that he will not see Rachel anymore. Since he is incapable of handling this, their marriage ends.
When Rachel's boss asks her to take his niece Emily to the opera on the same night Rachel has her first "date" with Joshua, she convinces Ross to go with Emily instead. She and Ross end up in a bed & breakfast in Vermont at the end of the date, and the rest of their relationship is similarly fast-paced.("The One With Joey's Dirty Day")
When Emily leaves to go back to England, Ross catches her at the airport and tell her that he loves her, to which she responds, "Thank you." Later she reveals that she is seeing Colin. However, she decides to end it with him and admits to Ross that she loves him too.("The One With The Free Porn")
Greatly bothered by the fact that Emily has to keep traveling back and forth between New York and London, Ross suggests they get married (despite only dating for 6 weeks) Emily is reluctant at first but agrees, and Ross gives a proper proposal.("The One With All The Haste")
Emily starts planning her wedding and puts her future sister-in-law, Monica Geller in charge of picking up her wedding dress. What Emily didn't know was that while Monica picked up the dress, she wore it and Phoebe and Rachel got their own wedding dresses.("The One With All The Wedding Dresses")
Rachel is very unhappy as she realizes she is still in love with Ross, and decides to tell him at the wedding in London. In London, the building Ross and Emily were going to get married in was starting to be torn down early which lead to a fight between the couple. Ross and Emily almost called off the wedding until Ross made it up to Emily and decorated the half torn down building so he and Emily could still get married. ("The One With Ross' Wedding, Part 1")
Deciding at the last minute not to tell Ross about her feelings, Rachel simply hugs Ross. However, seeing Rachel brings back Ross' old (and true) feelings, and instead of saying, "I, Ross, take thee, Emily...", Ross accidentally says, "I, Ross, take thee, Rachel..." ("The One With Ross' Wedding, Part 2").
Emily's jealous side to her personality is revealed in this season. The wedding continues and is finalized. However, feeling humiliated, Emily escapes the wedding party. Trying to save the situation, Ross asks Emily's parents to tell her he would wait for her at the airport, hoping she would still like to go for the honeymoon. After apparently getting stood up by Emily, Ross eventually decides to take Rachel with him instead - only to be seen leaving together by a late-arriving Emily. Emily escapes Ross again and runs into hiding afterwards.("The One After Ross Says Rachel")
Ross then returns to the states, attempting to reach Emily and persuade her to forgive him over the phone. When she finally calls him, he convinces her to come to New York. She agrees, with the condition that Ross will never see Rachel again. ("The One Where Phoebe Hates PBS")
She also convinces him to sell all of his furniture that came into any contact with Rachel and move into one of her relatives' apartments. The other five friends agree to support Ross as long as he is happy with being manipulated by Emily, but when Ross expresses his discontent with all the changes he has to make, the group helps him realize that he cannot meet all of Emily's conditions. Ross then tells Emily that he doesn't agree to her terms, and their marriage ends. ("The One With The Yeti")
Ross later finds out that Emily is getting married again, and because of this he begins dating Janice. The relationship doesn't go far after Janice can't take his negativity.("The One With Chandler's Work Laugh")
Later on Emily calls and leaves a message that she wants to talk to Ross about getting back together even though she is getting married. Rachel convinced Ross not to call her back.("The One With The Ride-Along")
Emily is sweet, smart, supportive and caring when in a positive relationship but she has trouble coping with adversity. She also has trust issues, can be very controlling, manipulative and makes very dramatic and impulsive romantic choices. She is also very unpleasant when she does not get her way as well as very unreasonable.
Emily is shown to have a good relationship with her father Stephen Waltham. Her relationship with her stepmother Andrea Waltham is unknown and nothing is known about her relationship with her birth mother and it's likely she has a good relationship with her uncle Mr. Waltham and her cousin.
Emily was introduced to Ross Geller by Rachel when she asked him to take Emily to the opera and this triggered romance. They soon decided to get married in London, but then Ross accidentally said Rachel's name and later they ended up getting divorced because Ross refused to stop seeing Rachel as Emily demanded.
Initially, Emily was fond of Rachel and was quite good to her. However, after Ross said Rachel's name at his wedding to Emily, Emily now started having negative opinions of Rachel and asked Ross to never see or speak to her again, something Ross was completely unable to do. Eventually, Emily realized that Ross was unable to stop seeing Rachel and she and Ross decided to divorce. It's possible that when Emily had doubts that when she was getting remarried herself or possible wanted to start over with Ross that she was willing to forgive Rachel.
- Actress Helen Baxendale became pregnant between seasons 4 and 5; as a result she was unable to travel to the US to do any filming for Season 5. Her only appearances were heavily swaddled in bedclothes, and she had to be written out of the series a lot earlier than was intended. Helen Baxendale was asked to reprise the role in Season 10 but turned it down to star in the West End play After Miss Julie, and because she did not want the same level of tabloid attention she received in 1998.
- Ross and Emily's marriage lasted about two to three months.
- Also out of Ross' wives, Emily was the only one whom he did not have a child with (Although Ross and Rachel got drunkenly married then amicably divorced, they had their daughter Emma 3 years after this event and out of wedlock, but later Ross and Rachel are remarried).
- No one knows Emily's birth mother's information and whereabouts.
- Emily's overly-paranoid, depressive and unreasonable personality could imply that being humiliated by Ross at the altar may have caused her to become slightly mentally unstable. Ironically, Ross later (by accident) caused a different woman to become mentally unstable in a later episode.
- Ironically, both the start and the end of Ross' relationship with Emily were done by Rachel: Rachel unintentionally set them up in The One With Joey's Dirty Day when she begged Ross take Emily out to the opera so she can meet Joshua at a party. And when she barged into their wedding out of jealousy, her presence resurfaced Ross' old feelings which distracted him into saying Rachel's name at the altar resulting in Emily divorcing him in a later episode.
