Erica was named after her biological mother, Erica, although both Erica and Joey appeared not to fully register Chandler and Monica's reasons for choosing that name for her: When Monica and Chandler tell Erica that they are naming their daughter after her she responds "Oh My God! That's just like my name!". When Joey learns her name, he says "Hey, that pregnant girl's name was Erica." Chandler responded with "It's a shame you two didn't spend much time together!"
- According to Monica, she had wanted to name her daughter Emma since she was fourteen, but she ended up letting Rachel have the name two years prior to becoming a mother herself when Rachel had trouble finding a name for her daughter on her own.
- Erica was named after her biological mother, similarly to another adopted character, Phoebe, who was also named after her biological mother. Both characters were born as twins.
- Erica would be 13 in 2017.
