 Albert had a stammer , which affected his ability to deliver speeches , and after October 1925 , Elizabeth assisted in helping him through the therapy devised by Lionel Logue , an episode portrayed in the 2010 film The King 's Speech . In 1926 , the couple had their first child , Princess Elizabeth – " Lilibet " to the family – who would later become Queen Elizabeth II . Another daughter , Princess Margaret Rose , was born four years later . Albert and Elizabeth , without their child , travelled to Australia to open Parliament House in Canberra in 1927 . She was , in her own words , " very miserable at leaving the baby " . Their journey by sea took them via Jamaica , the Panama Canal and the Pacific ; Elizabeth fretted constantly over her baby back in Britain , but their journey was a public relations success . She charmed the public in Fiji when shaking hands with a long line of official guests , as a stray dog walked in on the ceremony and she shook its paw as well . In New Zealand she fell ill with a cold , and missed some engagements , but enjoyed the local fishing in the Bay of Islands accompanied by Australian sports fisherman Harry Andreas . On the return journey , via Mauritius , the Suez Canal , Malta and Gibraltar , their transport , HMS Renown , caught fire and they prepared to abandon ship before the fire was brought under control .
