Mermaids was founded in 1995 by a group of parents of gender nonconforming children. The 2018 ITVdrama seriesButterfly, about a young trans girl, was substantially informed by Mermaids. CreatorTony Marchant worked with Mermaids CEO Susie Green, who had a consultancy role on the show. Marchant visited families who Mermaids worked with to inform the writing process, and cast members Emmett J. Scanlan and Anna Friel also met families involved with Mermaids. In December 2018, the charity was designated £500,000 in funding by the National Lottery. However, the funding was put under review after criticism of the charity, including by Irish comedy writerGraham Linehan, who created a post on Mumsnet calling for members of the forum to email their concerns the National Lottery. In response to this, on 18 January 2019, YouTuber Hbomberguy began a livestream attempting to 101% complete Donkey Kong 64, with a goal of $500. The stream became popular and raised over $350,000 USD for Mermaids. Among other guests, the stream featured an appearance by American politicianAlexandria Ocasio-Cortez. On 19 February 2019, the National Lottery announced that it would follow through with the promised donation. Starting from 2017, Mermaids reported that it and its volunteers were being targets of online harassment, leading to concerns by parents whose children are supported by the organisation. Green was accused of forcibly castrating her transgender daughter, Jackie. Jackie replied that the accusations were "incredibly hurtful" and that "If my mum had not helped me I would not be here today". Transgender journalist Paris Lees wrote that: "Susie Green is saving lives and I wish my parents had known about Mermaids when I was growing up". In June 2019, The Times revealed that they had discovered a data breach by Mermaids in which confidential emails had been made readily available through their website. The Times stated that these included names of transgender children and their parents, together with contact details and intimate medical information. The newspaper reported that there were also internal e-mails from the trustees that criticised the leadership by Susie Green, as well as criticism from parents. Mermaids issued a press release on the same day, which acknowledged that a data breach had occurred, and that they had informed the Information Commissioner's Office and had corrected the breach. The press release stated that the breach was limited to internal emails and that no emails to and from families were part of the information leaked; The Times disputed this.
