 She married her third husband, Morris Williams, also a solicitor, in 1955, though she continued to use her second married name, Puxon.She established a divorce practice and gradually built a reputation in family law; she represented the Rolling Stones bassist Bill Wyman in his divorce from singer Mandy Smith, and in "J v C" she represented an adopting mother in a case where the natural mother wished to regain custody of a child she had put up for adoption.In the 1970s, Puxon switched interests from family law to medical negligence, typically representing plaintiffs; her dual qualifications in medicine and law gave her a niche advantage in this area.
